I'm glad to hear that. I realize how lucky I have been with my Dad as opposed to the rough time I had taking care of my Mom (and Dad) full time for two years.
When he went into assisted-living six years ago Dad promised me he would make a concerted effort to be happy and he did become so. He ended up having to use a walker often and did so, adjusting well and not complaining. Then more than a year ago now he came down with COVID, broke an ankle and sprained another falling down in recovery (supported by two aides, and it's not like he's really big in any way) and has been bed-ridden ever since and in hospice for ten months. And yet. . .he's constantly pleasant. We talk on the phone every day and he continues to be an inspiration and education for me. The last five months or so we have been reading the same books together and discussing them, which is a fantastic thing I don't want to end. I visit him twice a week and we have a great time, especially when my wife comes with me and she and he share some great laughs. It's so distressing to see him bed-ridden this long, but he is the least distressed of any of us.
