Why Me?

Why do I attract the wrong kind of people?  When I ask this question, I am actually referring to when I am sitting on the train either going to work or travelling home.  I normally get on with either my book or my kindle and read for the 2 hour journey that I have to face.  Two or three stops down the line then the crowds start to get on.  First I get the ones that like to use me as a pillow.  I am not a pillow, I am a human being believe it or not.  I wouldm't mind but they sometimes even try to fluff up my shoulder!  Then there are those that do not care about those around them when they let all the bodily functions have a mind of their own.  May be a little apology when that happens would go a long way instead of me suffocating in their stench.  Then last but by no means least, there is the raving loon.  They sit there talking to themselves and answering themselves I might add, only when you answer them, thinking they are talking to you, they look at you like you are the mad one.  Please tell me why they choose to sit next to me?  I only want to get home.
