My grandparents who both have dementia and are going into a home next year have remebered it's Christmas and called us to wish us well...about eight times, forgetting the previous seven times they'd called.

My grandpa has sung carols down the phone each time and they are overjoyed we are taking them to our house on boxing day (every single time we tell them lol.*)

*They did enjoy coming on boxing day last year, but this will be the last time we have them over most likely.
