Goethe said, “Certain flaws are necessary for the whole. It would seem strange if old friends lacked certain quirks.”
Isn’t it so often the quirks of your friends that make them so fun to be around. Whether it’s wit or worldly cynicism it keeps you entertained and thinking about view points other than your own.
You are the same. Your quirks are what make you fun to be around and entertaining for your friends. Keep them, they are what make you, you.
