Of course you can use Sid or Jake! One of my good friends is 94 and lives in a nursing home. I'm not her family or even near her age, but I try to visit her as often as I can (I try to go every week) because her family only rarely sees her. She was my neighbor while I was growing up and we can talk about the "good old days." She and the other ladies perk up so much when I come in to see them. So, I think it is wonderful what you are doing to brighten up the day for these folks.
