Literally every romantic decision I made until I was 19. I don’t think it’s being “grass is always greener” to say I got every large (I mean, in context) decision wrong.
Also got a bollocking on a school trip for my “BOY BANDS SUCK” t-shirt because it was “sexual humour”, which I maintain says far more about the teacher who read that into it than anything else. Also what a fucking stupid t-shirt. Might as well have been “SHINGLES SUCKS”, it’s not exactly controversial.
