I always visit and take her for an outing on Sundays. Yesterday we went to a wonderful greenhouse in a great park. Two hours later she calls and says she would like for me to visit her sometime, that I haven't been to see her in many weeks. Highly frustrating. I mark on her calendar, I send pictures of our outings. What else to do? Grin and bear it is wearing thin with this constant barrage.
I do like Vicky's suggestion of an album. Even if your mother doesn't remember the outing, looking at the photos might just be relaxing.
