What is something you wanted as a kid and bought now that you're an adult with disposable income?
I really wanted a modded Xbox 360 when I was younger because I thought being able to play 'backed up' games and having a custom dashboard was really neat.
I ended up buying one last year to fulfill that childhood wish.
I didn't exactly buy this but I quit Catholic church and grew out my bangs, and bought my first pairs of bikini underwear, all of which was verboten for me as a youth.
