I think it’s funny how you equate being a (lower case) coward with being a dick. I will try to not take it personally. (that’s a joke)

I don’t review creative works by my friends, positive or negative. I will say “I read this book, but it’s by a friend of mine so I won’t review it.” I don’t know if that makes me a dick, but I’m definitely a Coward (upper case).
