It is suggested that on the 21st we volunteer to spend some time with seniors. You could volunteer to teach them how to use Facebook to keep in touch with their families. You could just visit with them.
With my mom living in an independent apartment I get to talk to seniors on a weekly basis. It is a treat. I learn so much - from their experiences.
At my mom's independent apartment facility there is a volunteer that comes in every two weeks - to do the resident's nails. How lucky she is to get to spend a great deal of time with the them. I think she benefits from her volunteering time more than they do.
