brothers

you are the sister of three sick guys, zach, phil, christopher are your half-brothers on your father's side, two of them were chatting, occasionally looking at you and laughing, zach was sitting next to you, putting his hand on your hip, not letting you leave, zach was reading another book, you started to say something, he interrupted in a rude tone telling you to shut up, you decided to ask phil and christopher
-Can I go?-
everyone said in one voice
Zach: No.
Phil: No.
Christopher: No.
