What do you think of making my sister move out?
How are you going to get her to move out?
By being a total jerk to her she will have to move out
It is rude to get your sister to move out by being a jerk to her. If you really want her to leave, you should talk to her instead of being passive-aggressive.
I believes in getting things done by being mean. I think it's a waste of time to talk to my sister.
Don't you feel the need to protect and look over your sister? It doesn't sound like she has done anything wrong. You should try talking to her before hand so she could make proper arrangements to look for a new place.
