And you talk like Indian (native american) stereotype.
How!

Or, perhaps it's like a Hollywood stereotype accent for an Asian sensei, like Mr. Miyagi.
It's also very similar to that.

Either way, you should be embarrassed and many people are chuckling at you.

Ah hermano… now you mock Native people

You sound like man who never sweat in sun or miss a meal.

You sound like a man who is clueless and doesn't know me at all. 100% bravado, 0% actual information

Maybe I no know theology… but I know when big bear snore.

Always quiet when priest betray family.

Always quiet when bishop mix oil like soup.

But when little campesino ask question?

Grrrr! Big bear wake up! Start growl in forum!

Hermano… maybe you not defender of truth.

Maybe you just forest animal trained to bark at peasants… and purr for hierarchy.

More like Tonto -- doesn't know how to stop while he's ahead.

Back to the topic at hand.

I think hiding things from children is a bad thing.  If you don't want your children to smoke then tell them.  If they ask questions, answer honestly.  If you sneak around, they learn to sneak around.  And always practice prudence.

You don't have to be blatant about it, but if a child finds you be truthful.  

The boy does know I smoke. He was with me when I bought the pipe. It is no secret, but I always smoke it after he goes to bed.

My worries are that he might get interested in the most dangerous kind of smoking (cigarettes) if he sees me smoking the pipe. Considering what some posters have said, it is probably no big deal. I guess it would be the same as worrying that he might become an acoholic because he sees my wife drinking wine occasionally.

My thought is his interest in smoking cigarettes would probably only come from his peers.  If his peers don't smoke, then he probably won't.

It's called incremental or creeping tyranny. It's conditioning. Understand, fool?

I bet your VO2max is pathetic.

Fool?    Thank you for your concern and obvious sincerity.  I've been following the shenanigans of the Money Master Mafia and the Black Nobility for 30 years.  I am well aware of their methods.

FWIW, I am in fantastic shape and am not worried about partaking of a little tobacco, or drinking a reasonable amount of alcohol.  I work on my feet all day long, running circles around my associates, most of whom are decades younger than I.  They whine about doubles at work while I happily work them all the time, remaining affable all the while, hour after hour, day after day.

I had to look up VO2max, as only young, modern wannabes even know or care about such meaningless metrics.  I also live in the woods, cut down trees, chop lots of firewood and, generally, do things daily that most moderns would consider too tough or beneath them.  When I drove a garbage truck and threw trash in northern KY (for a company owned by a rock-solid Catholic family), even the saltiest old birds knew I was among the very best at the incredibly hard job we shared.  Think before you speak; you'll live longer.  Smoke 'em if ya got 'em.

Godspeed.

Ok, chimney lungs.

Btw, can't you spend an hour with Our Lord while He suffers the passion in the garden? You're supposed to fast before and after the Holy Mass. Why are you smoking in the chapel parking lot? Can't you suffer your nicotine craving for a little while? You gotta have your fix over Our Lord?

Nicotine is not a nutrient, and smoking tobacco in general does not have any nutritional value. There is no food being consumed and entering the stomach, so there is no fast being broken. 

Fasting from physical "stimulus" that comes from tobacco is just as necessary as fasting from food. It has the same spiritual effect when offered up to Our Lord. You lose. Truth wins.

I would be grateful if you provided a source, specifically regarding tobacco/nicotine. Are you meaning this in the sense of impairing the use of one's reason? 

145. What is requisite to constitute a violation of the eucharistic fast?

 To constitute a violation of this fast, three things must concur:

1st. What is is taken must come from without. Hence the fast is not broken by blood coming from the gums or the mouth, or by the particles of food that may have lodged in the teeth the night before. But the fast is broken by putting into the mouth before midnight, sugar, gum, lozen- ges, ete., and swallowing them after midnight.

2d. What is taken must be swallowed as food or drink or medicine. Consequently a person does not break the fast if, when rinsing his mouth, he inadvertently swallows some drops of water, wine, or juice which have mingled with the saliva; nor again, if he does so when he applies postage stamps to his tongue before affixing them to the envelopes; or when he tastes wine, sauce, or broth; or chews tobacco or some aromatic plant, provided that he has no intention of swallowing it, and that he spits out the particles that are in his mouth. So too he does not break the fast when, in the act of breathing, he swallows a snowflake, a raindrop, a little dust, or a fly; nor even if it be tobacco smoke or smoke from dishes that are preparing; nor again if it be snuff which has passed from the nostrils to the throat and has then been swallowed.

3d. What is taken must be digestible. Hence the swallowing of a piece of stone, iron, or wood, of hair, or of a portion of a finger nail, would not break the fast.
