I'm finding the urge to tell my mom to leave.
That's odd, why would you want to leave?
Because they are wonderful people who are living with me
You should respect your mother more. It's rude to tell her to leave.
Listen to what I have to say. Don't you tell me how to talk to my mom.
I understand you may be looking out for the people who are living with you currently. But that doesn't mean you shouldn't show some respect for your mother. If you believe that she is going to disrespect your roommates, then you should have a conversation with her before she comes over.
