How wonderful it is to visit relatives we haven't seen for years. I'm sorry your aunt has Alzheimers and didn't know who you were. That's heart-breaking. And what a great surprise to run into someone else you knew while shopping.
I haven't shopped for pantyhose for years. I no longer wear dresses very often, so the nylon stockings last a long time. Since the younger generation prefers to be bare-legged, those stockings may not be easy to find around here, either. But I haven't looked.
