The problem I encounter with starting a conversation is that I have the idea that I'm telegraphing my intentions too loudly by doing so. (Hm, she's cute. Find a way to initiate conversation!) "Hey, is that ____________ you're reading? I've meant to look at that... is it any good?" -> trans. "Hey, you're cute and I'm trying to find a way to initiate conversation with you."
Like maybe women assume the only reason a guy would strike up a random conversation is that he's trying to hit on them. Pretty unfair assumption, I know.
