Unphotographable

This is a picture i did not take of an  Asian teen and a of his friends talking on the train, when a lady in a wheel chair interrupted and started arguing with the group over their use of profanities as her daughter sits below them. They sit in silent embarrassment   as the train reaches its next stop and they all exit. All but one who as he makes his exit, swiftly turns around and spits into the face of the lady in the wheelchair.
