She keeps on talking about how great life was when she was young. And she keeps crying and saying how much she misses my aunt's (her daughter) first husband, who died 30 years ago.
She doesn't even remember my name.

One time I told her my name, then 30 seconds later I asked her what my name is and she already forgot. And she's not even that old she just doesn't put an effort. She lives in the past and it's kind of annoying.
