Visiting an elderly parent

I am out of town spending time with my 90 year old Mom who I visit three times a year, but talk to weekly.  She lives by herself since my Dad passed away a couple of years ago and has adjusted remarkably well to living alone for the first time ever.  Since we talk often and she lives in a very, very small town it is always interesting to decide how to spend our time together.  My brother and sister-in-law live nearby and see her at least once a week and they take care of many things for her.

Since I wrote this before I left I don't know exactly what we will be doing this time.  Usually we go out to eat and perhaps to a play or art show if available and she is able to go.  We tend to run some errands as she doesn't drive any more and she usually has a project or two for me to help with.  I try to cook most meals to give her a break, but truly she likes to go out to eat since I can provide the transportation.  We may go visit my aunt and cousin over lunch.  I take walks if the weather allows and we have a meal at my brother and sister-in-laws.  It is pretty low key these days, but I am so lucky to still have her and she is so mentally alert and interested in everything. 

If you have an elderly parent how do you spend time with them?
