I can't speak for everyone. But I think quiet guys comes off as being an ass if they are not participating in a conversation when the other person is trying so hard to keep it going. The girl might want the guy to speak up too (equally) and want to know him better. I mean she already know what happened in her day, she wants to hear what she doesn't already know (which is what happened in your day and your opinions). It might depend on the girl. Maybe some girls do like quiet guys especially those who like to talk about themselves and dominate conversations.
