Here in the west when people reacha certain age, they feel they have to act all 'adult' and stuff like that. 'cant like cartoons anymore' 'cant hang out with friends at McDonalds anymore, but lets go to a 'real restaurant instead', 'cant wear 'childish' clothes anymore', or 'play football on a concrete little field'
In HK and Japan, people just do more what they want, like what they like, eat what they wanna eat, collect what they wanna collect, play what they wanna play, etc etc.
They're less hypocrite about being themself and liking what they like.
I like that. It's more relaxed and honest. I dont like it here in the west, where everyone wants you to grow up so very very fast.
I'm 31, but I still enjoy comicbooks and anime and collectible toys and videogames etc. Dont feel I should be ashamed of that either. I am who I am and I like what I like.

But when you say you enjoy playing Xbox, or reading Batman, or watching Ranma, people here will frown upon you. They dont get it.
