The Sibling Wars

Can you guess what happens next? If you have a sibling, you probably know that a couple of minutes after the fight to get in the shower, both of them refuse to go in! Now they fight over not going to the bathroom first, and the quarrel continues until a parent calms them down. Siblings are weird, aren't they?! They are the most lovely and most horrible people at the same time! And you know your childhood is over when you no longer hate your siblings.
