what is acting normal? how do you define normal? if someone slaps you in the face, isn´t normal to defend yourself, even slap him back? what is called "normal" is very relative. if you fallen in love for the girl, how the hell do you want to "act normal"? pretending to act "normal" is already a contradiction to yourself. be as you are, do as you like. don´t act out, don´t try to impress, good girls hate show off. just be yourself, natural. that´s more than enough.
