<human>: Condense the text into a few key points

I've always been a very obedient child. Never really drugs or smoke or got into any kind of trouble. I love staying at home also. If I were a parent, I would love to have a child like myself.

However, recently I've gotten into some argument with my parents over a very stupid thing: my hairstyle. I'm a guy with a medium-long hairstyle that suits me but my parents insist that I cut it short, because guys "should have short hair only". For the record my hair isn't even considered that long, but that's not really the point.

Here's the problem: I'm fucking 22 years old already. I never had this problem before because I was in school before and the school rules required guys to have short hair as well. I also considered the fact that I was not an adult yet, so I didn't mind listening to my parents. But now that I'm an adult, I find it ludicrous that they would even care about my personal appearance choices.

I come from a conservative Asian country where children move out from their parents much later so getting my own place/moving out on my own is out of the question. I'm also in university now and they're paying my school fees so I'm pretty much stuck with them. It's infuriating that I even have to get into an argument with my parents at the age of 22 over such a stupid thing. How would you suggest I go about resolving this? They're threatening to cut off my internet/phone unless I cut my hair short, and I hope it really doesn't come down to that because I look extremely bad with short hair. (mine+almost all my friends' opinion) I would also like to add that I've spent my whole life giving in to people and not standing up to my own choices. I've never once rebelled against my parents/did anything to upset them so for once I'd like to have a say in something like MY OWN personal appearance.
