You might search for other threads -- I know we have discussed it. The gift of your time is often the most precious, whether to help them get out somewhere they wouldn't otherwise, or just to hang out at home and help them with chores or setting up something new that needs doing. It might even mean getting some others to come by the house to socialize, while doing all the work involved in hosting, if that is welcomed.
Truly, if you ask the family that question in a way that shows you really mean it, one of them probably has some ideas!
Thank you for asking the question and wanting to help your friend.
Best,
Laurie
