I have to agree with independence.
I lived in a pretty strict household when I grew up. I had to be in bed by a certain time unless I had a damn good reason not to be (virtually the only acceptable reason was school). Our computers in the house were in a communal area that anyone could see so it was not private at all, so if I wanted to spend late nights gaming or chatting or looking at porn (girls do it too you know), I had to always be conscious of the fact that my parents could walk in at any time.
Getting a laptop helped the issue a little bit since then I could just close the door to my room and turn the lights off, but it's not the same.
Now I sleep when I want to, I do what I want to, when I want to do it. I clean when I want to (which is actually quite often). I cook what I feel like eating. I have sex or masturbate when I feel like doing those things. WHEREVER I feel like doing those things. And I can be loud!
So I guess being an adult has its benefits. I still think the responsibilities suck (bills and mortgages and taxes and all that other lame adult shit), but I GUESS it's worth it.
