your brother had 2 close friends. Xavier and Zavier, but they are your enemy's

one night you couldn't sleep so you went to the kitchen to go get some water, and you see your brother, Zavier and Xavier on the couch watching a comedy movie.

when they noticed you they offered you to come join them, so you did, you took the only seat in between your enemy's and eventually Xaviers hand is on your thigh and Zaviers around your shoulder
