hum.. I would say yes but in small dosages, in this case I would say less is more showing them that you are crazy for them but can control yourself. If a girl acted like that around me I would be flattered.
not sure if I'm good looking enough in your mind but that's my opinion.
Sometimes it's hot. Other times it's creepy. One time at work this girl was crushing on me and after I got off work, tired and ready to head home, I found her sitting on the hood of my car out in the parking lot waiting for me to get off. Just creepin...that was pretty annoying.
