"is it normal that i think i have a chance

So i was hanging with some friends, and one of my friends said he was going to meet two girls, one was his friend, and the other one was the girls friend. So we met them, and the one that my friend didint know was really good looking. However the next day i met same fried and he told me that the girl i said was good looking had told her friend that she thought i was good looking. So ofcourse i were happy as fuck. But the thing is i dont have facebook, which she didint seem to like. I dont have facebook, not bcs i dont have any friends, i just dont have it yet. But one of my other friends have some pics of me on his account. They all got comments and shit :D. So im gona get facebook and i have the pic im gona use in my cell. And she also wanted my friend and me to come over to her place to watch a movie, nothing special happened tho. I dont have her number, but when i get facebook ill add her. IS IT NORMAL for me to think i have a chance?
