My mom can go from pleasant to argumentative in a moment's notice. It'll usually start with a simple statement or question from her which I'll respond to. This is an actual conversation we just had after laughing over a different topic 5 minutes ago:
MOM: I wonder if the boys are still working. (The boys are her grandsons that both have temporary jobs)
ME: They haven't worked for 2 weeks now.
MOM (angrily): I think I would know they go to work everyday.
The End. The lights turn off. Curtains close. No applause because the audience is befuddled as to how they bought a ticket to what started as a comedy but abruptly ended as a tragedy.
This makes me wonder if she knows her memory is bad. Are dementia patients aware of their condition?
