the letter is a good idea. I live in a rooming house and like to keep to myself. I have found that the more you try to keep to yourself the more people want to talk to you? let them know that it takes all your energy, even if it is just people talking to you and you do little talking. many people have come and gone, and a lot of people want to talk to me and not talk to everyone, they would knock on my door to ask me something even if their are other people around. they would bypass them(in the general area) and knock on my door. I find that making a joke out of it will get them to stop and not make me look like an a- hole in the process.
the caregivers are who you want to start with.
