My dear friend please never allow yourself to appear like an ex-convict by not attending to your hair or beard.
I am baffled when I see some young men who refuse to shave in due time. I don't know whether it's a new form of revolt or sense of arrival. A face that is not properly shaved is not only repulsive but speaks of so many evils about you.
Why not claim a gentleman even if you're not one?
