If you want to know the scale how faster one falls in love in scale 1 to 10 ,I would say guys are winner with getting 10 points , girls badly behind with hardly get 2 to 3 points. See, such question is invalid to ask because guys are very innocent. They have very big n wide heart. They dont wish to hurt any girl's feelings. First girl he looks at n if she smiles , means guy is out . Guys falls in love at a time. He is so generous ,for him girls look is more then enough to fall in love. Its universal truth guys decide by eyes n girls decide by ears. In case girl moves further n after smile , if she talks a little bit with that guy means , guys confidence boost to highest level and he feels proud of his decision n starts telling his friends , please stay away with that girl , she is your sister in law. And if girl continues talking for few more days ,with same guy, he starts thinking about name of their children. To be honest , I am holding myself from falling in love with you after looking at your profile picture in wonderful red top. You looking gorgeous. And beauty with brain for placing such wonderful Thread. But I am not that cheap like most guys who falls in love at a first sight. Thank you for such wonderful Thread n giving us guys opportunity to read girls opinion , how fast they falling in love in case , ever , they fall in love. Though I doubt about it.
