do you mean what if the girl you love gives you angry looks? If you do first do you know if she loves you or are you not sure. because if she does shes just mad at something you did she come around but if you don't no she might like you as well have you done anything to annoy her because she might just be upset cause she thinks you wouldn't ever like her in that why or she could just not like you because you mean to her or something. And if you don't mean what if the girl you love gives you angry looks what do you mean?
he would probably feel guilty
It means that girl is either desprate, MADLY in love, or is not playing "hard to get" P.S.- If you truly want a guy to like you, be your self and don't go for looks (and play "hard to get").
