> Jane D: you men are all alike. A man can never help a woman. 

All, never, always, are absolute universal quantifiers according to [David Burns M.D.][1]  

They're thought distortions. If she thinks this way to herself, no wonder, she feels the way she feels.  

If she doesn't respond to that argument, just get some big headphones, wear them and listen to music/podcasts when she's around. 

Or use the fog and broken record method from [Manuel J. Smith][2].

If she upsets your mother, there is really nothing you can do about that. Your mother makes her own decisions about who she talks to. But I suspect that if you don't let her upset you, your mother won't be as upset either.
