There's a big difference between actually being a victim and just playing one. In the first case, someone wronged or mistreated you; in the second, you just don't like the consequences of your actions or having to take responsibility for either.
Your sister is the one who f***ed up the relationship, if you want to lose me because you both need to mature and grow up that's your choice. I don't like who you're becoming to be honest. You're turning into the kind of immature adult(s) I can't stand. I'll be here when you wake up, not because I'm desperate, but because we're family and we were never supposed to quit on each other.
You didn't tell me he was coming like you were supposed to, you haven't told me when he's leaving, which out of common courtesy you should. I want to know how long that "limited length of stay" is. He's been here for a week, I'm sick of him and I want him OUT!
