When first introducing the gf to your group of friends and one of them isn't listening to what you are saying so instead of saying her name he starts to call her as my sister. [spoiler]as if I would be doing things like that to my sister if I had one[/spoiler] This just happened. Your house sitting for your gf's parents and she Skype calls you saying that she cheated and she's breaking up with you while in there house and you still have another week to go till her parents come back home.
