Wait, is his wife staying over at your place as well? Or just your bro & mom?
And again, whether you want to have them over or not is irrelevant. You CAN'T have them over as it is against the rules & guides of the complex.
His wife is at her parents'. I'm willing to allow my brother to stay for tonight, as right now he has no other place to go, as his own in-laws can't put him up. He's even considering a hotel right now. But the fact of the matter is that my mom needs to be gone by Friday. I had told my housing manager that she'd be here Tuesday to Thanksgiving. Thus, after Thanksgiving, she needs to go.
I can't keep her here for the weekend, along with my brother, just because his selfish wife wants to stay with her mommy and daddy because she refuses to grow the [tornado fang] up and make a [tornado fang]ing sacrifice for once in her [tornado fang]ing life.
Can't you get your landlord to have a yelling match with her?
Housing office is closed for the holiday weekend.
