On the one hand, I understand your frustration because I've felt the same way about my grandmother (91) MANY times. Her issue is that she tries to do things that she probably shouldn't be trying and then gets hurt, but doesn't learn from this and repeats the process again. For example, "I was gardening outside...mowing the lawn...bringing laundry up from the basement, etc. etc. and I fell..."
On the other hand, it really seems tough to get old. My grandmother likes her independence but can't really have it anymore, and sometimes she gets lonely sitting at home without a means of transportation so as aggravated as I get with her sometimes I have to try to remain patient. We really do pay the most attention to her when she gets hurt or is sick, etc.

No one likes talking to her (except Jenn of course) because all she does is talk about her pills, bodily functions, "pain", diet, sleep, bodily fluids, ect.
Nothing else. No joke.
This isn't going to change. This is all I've heard about from mine since I can remember understanding language
