People who work in nursing homes can tell you how few visitors some residents get, even on holidays. Maybe they have no people left to visit them. Maybe their families live far away.
In your holiday activities, maybe you can fit in a visit? Ask at the desk who might be able to use some company. Bring a piece of pie or some cookies, but all you really need is yourself and a smile!
If you have children, bring them along. My adult children remember this activity with fondness. (I always wondered if they would grow up resenting me bringing them along on nursing home visits, so I was glad to hear them speak of it positively.)
