so there is this guy that i really like and well he have the same birthday, we listen to the same music, we have alot in common. Than one day screams across the room he was like hey Emilie! since we have the same birthday are we twins??!? and im like okay i guess.. then the next day he tells every one in my grade that we are twins! and im okay.. im actually realyy quiet around guys.. In one of my cles in the same week that he said that i was his "twin" the teacher made a seating a chart and she puts us next to each other and he was like hey emilie i you sit next to me and in my head im like yes! and then him and i have the same phone but i dont have his number!! and i want to be his friend or maybe more than that. In my history cl i catch him looking at me like 3 or more times in one cl period and he does talk to me and he allways can eathier put a smile on my face or laugh.. im just really courious does he like me!! does he seem like he likes me or not? i really want to know and im really really really scared to ask him...!! what do you think!
