Some friends come into our lives for just a short time. Others come and stay forever. Think about your closest friends. How long have you known each other? Some people say that their spouse or family member is their best friend. Others say they have known their closest friends for many years. And some great friends haven't known each other all that long, but knew right away that there was a connection, or bond, between them. Could it be that there is a twin spirit out there for each of us?
