You are taller than the slide at the McDonald's playland. Your parents' jokes are now funny. You have owned, and since disowned Michael Jackson's Thriller. Christmas starts to piss you off. You would rather wear your dirty clothes again, 'cause mom is not there to do your laundry anymore.
Naps are good.
Hitting girls is no longer considered flirting. When you know that the machines in gas station bathrooms don't dispense balloons. Playboy's Playmate of the month is younger than you. You actually buy scarves, gloves, and sunscreen. Your idea of fun parties now include Chips 'n' Salsa and Snapple.
