I'm going to kick my brothers and cousins out of my room
Why do you want to kick brothers and cousins out of your room.
Because I don't like my brothers and cousins.
You shouldn't boot them out when they are visiting. Just wait for their visit to end.
Okay but I am not going to stay around them, going out out of the house for awhile.
Now you're talking. Going out of the house will help you to destress too and be calm about it. There is no reason to kick anyone out, its your personal opinion of them that wants to do that.
