It's in 2 weeks.. If I ask her if she wants to go she'll fret about the decision... I don't want to be mean, but she hasn't seen her nieces and nephews (my cousins) in probably 15+ yrs, she get really confused... If she agrees to go, I can guarantee she'll wake up that day with a panic attack and tell me call them and say she doesn't feel... I don't want the pay for a meal she won't even show up for... But I don't want to make the decision for her...
She won't even know the party happened..She's the only one invited , well me of course so I can take her... I don't want to go,, It will just be added aggravation for me...
Mom won't know the difference, won't ask or question why she wasn't told, etc. If it ever comes up; just redirect her.
Sometimes its okay to selectively provide information especially if it makes the dementia person agitated, fretful, etc. Its just not worth it in my book.
