So, just off the cuff, which is the more grave sin? A kid vandalizing a car with paint (I had that happen to my car, an hour with some polishing compound and it's good as new)...
or an adult man driving around town yelling 'Suck it!' out his windows?
This reminds me SO much of my first Catholic pastor, it was only after a few years of his 'care' that I discovered that he was actually supposed to *absolve* me in confession.
