When physical visits happen, TAKE PICTURES! For now, these can be reminders that someone did visit, and later, they will be valuable memories for those who visited.

I agree with Dianne. I say something similar. When my mom wants to go “home” I say something like I’m really tired and could we go tomorrow…or some other comment that satisfies her.
It usually works. I know it is hard.

I would just acknowledge his comments and say something like "Oh I know, she must be busy"? Of course it does no good to try to remind or explain, at least it didn't in my case, though there were times I did just that. I finally learned to let most everything go. I know it's hard though.

When John has made similar comments I have said "sounds like you miss-----do you want to give them a call?" It seems to help whether we call or not. I've also said "sounds like you feel lonely...I miss-----also...let's call them and say Hi". Sending support.

My husband does the same with our adult kids. I have no answer. I tried telling him they were just here but he doesn’t believe me. I hate that he thinks kids have forgotten him😡
