Friendships

Dear Diary, Why is my adult life getting harder each day? Take for instance the fact that I can't just smile at the lady in the seat beside me and become her best friend. That is how I became buddies with Grace. Why can't I brush past the neighbor downstairs and next thing I know our kids are running everywhere playing. What has changed? Even my so called Facebook, twitter, BBM friends seem fake? Why? Am I missing something?
