When sidewinder tells "listen to the girl", he's also saying (I guess) you must listen to her for the sake of the conversation, as in, don't interrupt her when she's trying to show what she's worth in order to impress you. When she talks about her trips, etc.

Don't be a fucking psychologist, but don't talk about yourself, let her do the talking about herself and qualify once in a while, it makes her invest more on the interaction with you, thus in you.

At least that's what I understood, if that's not the case, then it should be on the list.
