Yes I agree with Yoda about personal boundaries. I remember you mentioning this older gentleman before and he's probably lonely too. He most likely felt you're kind, which is a rare commodity these days. If I were you I would get one of those do not disturb signs ' and hang it out when you want privacy and rest. If you have a messaging system let that take the calls and turn off the ringer - just don't forget to turn it back on lol. Don't be afraid to say no - it's one of the greatest gifts you can give yourself.
