Usually, they say something like, "You shouldn't smoke; it isn't good for your health." My response has always been, "You shouldn't tell people (you don't know very well and who are 6'3", 200+) what they should or should not do; it isn't good for your health."
LOL!
And yes, I DID laugh out loud at this, so I am using that worn-out expression here for good reason.
And it's an even worse idea to do this when the person is Irish/choleric as well (but I repeat myself?)
The Irish practically invented the pub brawl. And for those new to CI, I can talk about the Irish because my last name begins with Mc and my Dad's family is from there, several generations back.
Stereotypes are true, more often than not. Or the stereotypes wouldn't "have legs" -- they wouldn't last and persist like cockroaches.
Blacks DO like fried chicken and basketball. Irish DO like to drink and fight. Germans ARE very detail oriented and make good engineers. Italians DO tend towards art.
And they say Trad Catholics are a feisty bunch, always arguing and having a hard time getting along -- that a Trad firing squad would be in the shape of a circle! Imagine that stereotype!
