We know it sounds very grade school and some girls hate this reference, but it is actually true. Some guys just don’t know how to get round trying to flirt with you or talk to you so instead they tease you to get your attention. This may seem cute, but not all the time. It can get pretty irritating but that’s the goal—not to know that you like him. It’s like their camouflage in hiding their feelings.
When a guy likes someone, he wouldn’t leave unless he sees your smile dashing on your face. It may also be a hint that he’s building his closeness with you by initiating a tease competition.
