Yeah, for your mother definitely makes sense to already have more than one weekly phone call, but I was thinking about other family members.

Reading your post, it seems Facebook is a bit of a recreational activity to keep them sharp and social, which is good. What I was thinking is whether you need to participate in it, since the people this age I know is more than willing to keeping me up to date on all interesting stuff by talking. But of course each family is different so I'll just assume you know what you're doing!
