I try to do what I can for my parents. They still live in the same house I grew up in, in the same small town and really, considering their age, do pretty well. There are the usual aches and pains that come with old age and some memory issues too, but they take care of each other.
Yesterday, I took them some food I had been storing in the freezer. Just some meals that I cook and then put a portion aside and save in a freezer container. It's a small thing, but it helps them to have a few meals to pull out that are readymade and no trouble to reheat.
We had a picnic at a pretty park yesterday and sat and talked for quite a while. There is a nice pond, walking trails and even an old mill. I encourage them to get out of the house as much as possible and I think this reminded them of a nice place that they could easily go to. They are still quite active and do walk most days, but a change of scenery is good for anyone.
With elderly parents, who still live alone, there is worry most of the time, but you do what you can, to stay involved and keep in touch. As with anything else, it's the little things that matter the most.
