My mom is 89 years old. She seems somewhat depressed and becoming forgetful. She has always been somewhat difficult and critical. She tries her best not to bother me. In fact, she never calls. I always have to call her. We live in the same time. I try to call her at least everyother day. I invite her to dinner with my family -- she loves her grandchildren:). It almost always ends on a bad note. I'm trying not to be selfish, but if I quit teaching daily to spend more time with her, I'm concerned it won't be good. On the same hand I'm concerned about her.
