Why is it when a person sits next a person on quite a full bus do they jump up at the first opportunity to sit in a empty seat ,I notice it happen quite a lot and thinks it looks like the other person smells so bad they can't bear to. Sit next to them ( it happens to me and I know I don't smell) also at my bus stop there is a group of very chatty friendly women who when the bus comes all sit in different seats am I the only one who thinks this is weird ?
