How do you get an Angel?

Do you just wait for someone to offer, or do we ask? I have always been unsure of this?

Sometimes someone will ask you if they can be your angel, but sometimes you have to ask. Some people are afraid of asking. I asked someone who is seein the same Dr. as me and lives near the Hospital, rather than someone who live near me. But it really doesn't matter, as long as they can get in touch with you or your relatives or the hospital for updates. Patty
