So, make sure you're phoning people then. They might prefer you to be there in person, but a phone call is better than nothing.
Oddily enough we already phone our relatives. Since my dad died, my mum goes out 7 days a week because she can't face sitting looking at his chair. She's on 8 different committees, does multiple voluntary shifts in multiple charities, helps out at various church run things and socialises a lot.
I already phone her a lot, sometimes multiple times a day because she's on anti-depressants and has enough pain killers stockpiled to kill an army platoon.
Me phoning is not going to compensate for the other stuff.
