‘OMG, what are you doing here?’
In our childhood, all of us have this experience. All of us used to believe that our teachers are some sort of different human beings who live in and for the school. But this belief is broken down after we saw them like other ordinary people at the supermarket.
Maybe this doggy just had the same experience. He saw his favorite groomer outside the pet salon for the first time. Probably he is trying to ask him, Oh Man what are you doing here?
