I'm going to kick a girl out of a group chat.
Why are you kicking her out of group chat?
Not interested in hanging out with her anymore, she's boring.
You don't have to like everybody but you shouldn't kick her out of group chat, it is not up to you. There are other members and they might be upset about it.
I'm confused now. What do you want me to do?
Excluding one person from a group isn't fair. You could leave the chat yourself.
