I have had to change my perspective on Dementia in order to deal with this situation. When Mom is sitting with the other residents during activity time, I listen to her having her own repetitive conversation, even while her friends try to engage her in theirs. It reminds me of the group therapy scenes from One Flew Over the Cuckoo’s Nest.
I need a bumper sticker that says: “ You win! You’re better than me! Can we please move on now?”
