Family isn't always blood. Over the years I have picked up kids (and adults) who failed the parent lottery and taken on active and consistent roles as a close mentor. A few years ago I picked up twins who are now in University. One spent the summer with me(first time) and is returning to school tomorrow. I just took him on a grand vacation to meet my family in Canada, and show him what family could be. We had many family parties and dinners and we got to spend some time seeing a bit of Alberta including the Rocky mountains.
