I have discovered that I tend to overestimate the level of friendships in my life. Sometimes it even makes me wonder if I really ever knew the people in my life I had always considered to be close friends. I look back and ask myself if I ever really knew them at all. I've also discovered that I still have that tendency as some of the people I consider close friends don't really react in the same manner. Ergo, I must have overestimated that relationship, right? It's a somewhat embarrassing realization.
