One thing I recall is riding a bike to the store to buy shit because I was hungry, and I couldn't decide what to get for 5 minutes. Eventually I made up my mind, and when the cashier finished scanning all the items, I realised I didn't bring anything with me, including my wallet or phone. No backpack too, so no way to transport all that stuff back home.
"Uhh, sorry I uhh think I forgot my wallet... I'll be back soon..."
This wasn't a supermarket or anything, it was a local shop in a small village, the cashier knew me.
I rode back home, got my backpack, returned and paid.

Driving a car feels like you've become one with the machine. Nothing happened but it's dumb, don't do it.
