Having 23mm (35mm equiv) lens means I have to get pretty close to the subject in order to take a photo. That is not a problem when the subject is not a live one. But when it comes to other person, I have to invade their comfort zone.
The lady in the above photo was not quite comfortable with me being in her zone. I did not have the intention to take a photo of her working. I just wanted to take a photo of the hat she wears.
