One time in university I got a nasty stomach virus and, after days of weakness and eating jello, I finally ventured outside to walk to school. I was so weak that half way there I had to stop and lean against a tree to rest. That tree was so solid and so there. That was the first time in my life that I realized how important it is to have something (and of course, more importantly) someone to lean on. I also realized how important it is to lean. Sometimes I forget, but the tree makes me remember.
