You made me laugh!
I laugh at this because, my grade school poster board one time was about street racing..lol
While everyone else did something normal & cliché like you say, I did mine on something that, as a whole lifestyle, is considered to be on the otherside of the law (but not so as I was explaining). Emphasizing safety but also freedom of choice, especially free market (race for money).
The whole time I could feel the judgement from the other kids, parents, and teachers
I had to spin it saying "don't street race, take it to the track";
But I knew all the parents would speed to get to work, or not stop at a stop sign, etc. and when I bought that up in a non-direct way, they didn't like that lol
As you say, life is a poster board.
Make it your own, & don't give a fuck what others think of you. I sure didn't
Makes even more sense why I'm here 😎
