My sister and I are like this. When she lived at home it was horrible, we fought all the time. Now that she's not here anymore we really get along. For a while she wanted me to move in with her so I could go to school in Philly too but I knew that would never work out because we'd kill each other.

Also, my mother and my sister are like this. THey still fight a lot but she really can never move back home because there would never be a moment of peace again.
