Alcohol - I used to think this was so great, but now I can go months and months without having a drink. Yeah, I'll still drink occasionally and wipe myself out, but it's no longer the basis of my Friday nights. It's pointless.
Fireworks - I used to like them when I was 10, but they're so bland now. Give me a good lightning show any day of the week! In fact, summer is approaching in Australia so I'll hopefully see a few electrical shows.
Gossip - My mum is huge on the gossip scene, always trying to sprout some knowledge on who's getting a new couch, or who's going to jail, and so on. I don't care. It doesn't concern me so I don't give a hoot.
Cars - As a male, I'm supposed to be interested in cars. I'm also supposed to be interested in modifying them to look cooler or sound noisier or have a "fully sick" subwoofer in them or whatever. That really doesn't bother me one tiny bit. I just want a car that'll be reliable and have as little maintenance as necessary. A girl once told me I was "brave" for saying I didn't like cars...I thought I was just being honest...?
