Work vs school, sex and age (forum posts)

why work is better than school - there's no homework, once you go home you can leave it all behind until your next day at work; you get paid for all the work you do... (and more)
Sex vs Dating/Marriage - My question is: can two people maintain a purely sexual relationship, where they are not friends at all? Would you consider that acceptable or superficial and wrong? Why?
Age of majority - The day I turn 18....I can just leave? Stop going to school, stop going home to my dad.....could I just, walk out the door and never come back?
