Thanks for your reply Cheryl. He's divorced and it doesn't sound like he has a main caregiver. He drives ~60 miles one way to teach at our church and I don't think that much is knows about his private life/friends. Even if he has a friend or 2 to help I don't know if they would have the understanding/experience of what he'll need. We do have someone at church who is a hospice nurse and I think she's also offered to drive up and help out.
Someone mentioned that he might have a place to stay at the hospital while undergoing tx (?). I'm hoping to hear back from him to get more details. I've offered to go up when I can and do food shopping/blend things for him (whatever he can eat), etc, but I put that in a letter that hasn't reached him yet.
Aquaphor sounds like a good idea :-)
Thanks again!!
