Personally, I don’t put girls in the passenger seat of my car that I don’t like. All of my girl friends are girls that I would date if I ever got the chance to but can’t for whatever reason. If a quality, unattached guy is choosing to spend his time with you rather than to be alone or with his guy friends or with a different girl, then chances are he likes you.
Singing is something I often do just to cover up what might otherwise be an awkward silence. Also, I need the practice if I’m ever going to be the next American Idol!
