Sorry to hear about that.
I worry for my Fathers generations also, they are all in their 70s and 80s. We have my 74 year old mother isolated, we only visit her with mask on.
She is handling it good. She is sewing mask for family members.
We got to face time my 97 year old mother in law. First time we saw her in three weeks. She was eating lunch. She said she was fine. Then went back to eating lunch.
She is very funny.
