Whose friend?

Whose friend are you? We often ask this question to the person whom we don't know. Then the answer is former motorcycle gang.
In the middle of the night, before dawn, in the bar and with those kind of person, how shall we regard him?
We have no another way to recommend him as the person, following the proverb, "A bird with a feather gathers together.".
He should remember himself to be only a performer similar with street ones and to be a person far from dignity nor character.
We have been fed up with trifle and boring stories.
