It is actually beneficial to make bad impressions, I think! If they know you when you are at your worst and they still want to be your friend, that is how you know that they are loyal and true. If they meet you when you are happy and sober, they may not be so happy to know you when you are sad and drunk.
What would you do without me to tell you the truths of the world, mon frere? You drink too fast when you are troubled, you do not enjoy the wine. Good wine is for enjoying, bad wine is for getting you drunk.
