I am somewhat more mercurial in my relationships. I really don't have a relationship with my family with a exception for my mother and even then its just the occasional phone call or letter. As for friendships, I have had many friendships over the years, mostly lasting a year or two before either I move on or they do at which point I just make new friends call it a day. I don't find it draining at all for each day brings something interesting to the table.
