"...most illegal thing you did as a teen?"

I guess I'd have to look up the legalities of all the activities.

Likely class A misdemeanors involving no drugs, no alcohol, no petty theft, no criminal mischief.

I was using a fake ID to get into a dance club, harboring a runaway, was a runaway myself, and was working with a professional producer of raves to promote and run the raves (we rented out the warehouses, hired the DJs, setup the warehouse, took them down, etc). Which at the time, for y'all millennials, was illegal. :S

Now that I think about it...u/curiousindividual1 278, you haven't said what yours was...as in, what alcohol you made.
