Hi,\nThat isnt a dumb question. \nWell there are basically 3 types of boys. The 1st type is the shy one. If that kind of boy likes a girl, he would shy away from her and become tongue-tied and uncomfortable in her presence. Otherwise, he could be quite outspoken and garrulous.\nThe 2nd type is the guy who tries to impress. The majority of boys belong to this class. This type of boy will start showing off in front of the girl he likes. He could make jokes or show off his biceps or his brains, whichever be his strength.\nThe 3rd type of guy is the brat. There is a saying that a boy teases and bothers you only because he likes you. This is pretty true, but it isnt always true. A guy who keeps bugging you could like you, or he could be doing it just for fun.\nIt isnt neccessary that a boy would strictly adhere to any one of the 3 classes. Usually, it is a mixture of the 3 classes. That is just 1 factor which makes love so unpredictable.\n\nWhen I like a girl, I usually get a little shy and I might show off just a little bit. You just have to have a good intuition. Take a look at his body language, his eye contact, his rate of breathing etc etc. Usually, I can tell if a girl likes me. You just have to keep your senses open.\n\nWhen you know for sure that he likes you, then you could show your interest in him too, through subtle gestures and body language, and then wait for him to ask you out. Or you could make the move yourself and ask him out. It is all up to you.
