What about your mom? I am flexible.

Just let your pops know that she won't be around for a few days and then just break it to him slowly that he might get served with divorce papers and an eviction notice.

Tell him to don't take it personally, cuz you are helping out a friend that has been going thru a period of depression and that if I spend a few minutes with your mom's it might elevate my mood.

If that doesn't work, just tell him directly to fuck himself and fuck off.

Don't keep me waiting all day fucktard.
