'You don't have kids, so you can't talk.'
Really? At which point did ultimate knowledge of the universe come to you? Having sex didn't do that for me. Automated biological processes like breathing and pooping don't fill me with ineffable wisdom, so pardon me if I harbor some SLIGHT doubts about whether or not the automated biological processes of ejaculation or gestation rendered you omniscient. Making kids is not difficult, almost anyone can do it. And what's so special about taking care of kids? They're nothing but screaming poop factories for the first five years. After that they're messy argument machines. Don't tell me it will redefine my life's purpose. My life is okay the way it is, especially since it currently involves zero shitty diapers, almost no three a.m. wake-ups, and zero discussions about why you cannot borrow my car. I fully intend to keep it that way.
'Your music is annoying.'
Said your parents, and their parents, and their parents, going back forever. There's no surer way to determine the average person's age than what music they like.
'My kid would never do that.'
Well, I just watched your little hellspawn do that thing. Reevaluate your situation. Denying facts helps nobody.
Bumper stickers that say, 'My child attends ___ middle school.'
So you squirted out a kid. Big deal. So have billions of others. Your kid is mediocre, like billions of others. Know how I know that? If he were exceptional, you'd AT LEAST have an 'honor roll' bumper sticker. Stop being so proud of mediocrity, you moron.
