I will always try to be friendly but honestly within a few seconds I have pretty much decided! There are certain deal breakers, each girl has their own, there are certain things we are willing to compromise on. I personally prefer guys much taller than me, at least 6ft however if their personality is good enough then so is 5ft 10! lol Some advice for you boys though...smelling nice is definitely a good thing. I have a friend who always smells so good! He basically gets big hugs from every female he knows, purely as an excuse to sniff him. But keep it subtle, we do not need to smell you from across the room!
