Sorry to all the only children out there, but siblings are just the tits. If you've got a good sibling, you've got a partner in crime and an ally to fight against your parents and shitty relatives.
Some people are unlucky and don't get cool siblings to bond with. They get a nark or mamas boy, and don't have the pleasure of enjoying the presence of a dope ass friend living under the same roof.
So, if your 10-year-old brother gives you condoms or salutes you while you're getting laid, then you've won the sibling lottery. Seriously, take the time to be like “thnx lord” every single day.
