Enemies?

Angelina and Bill were very rivals; he was always teasing and provoking her. But she had a problem: they lived in the same building and their mothers were very good friends
One day, Bill's parents had to go on a trip, and they couldn't take Bill, so he had to stay at Angelina's house, and worse yet, in her room since he refused to sleep in the living room
-"Let's see if you don't bother me"- Bill says, lying down on his bed
