He has never ever shouted at me. Not a single word of anger crossed his lips wen I took that picture.

Actually his is a darling of a man, so nice and friendly with such an expressive face. He sells the Big Issue I buy one from him every time but never accept the magazine but I do get a photograph instead. He asked me what expression or pose I wanted. I told him to just go for it and this is what he came up with.
