How much do you believe in love at first sight?

I believe in it because ok here is my story it was still summer a couple of weeks till school started and my family and i went to church on Sunday. We where like in the back rows and this family comes and sits right in front of us. They had 2 boys and 2 girls. There was a older brother and a little brother like 11 and the older boy was like 15 or 16. At first i thought he was sorta cute. Then 2 weeks went by and we went to church again. The family came again but they sat on the other side of the chairs and when ever i looked over there the older boy was staring at me. Then school came. The family was new here. Ok then a couple weeks past then one of my friends was dating his little brother and she was at my house and she had her phone with her and he told her if i wanted to date his brother and i said i don't know. Then a couple days past then he asked me again and i finally said yes to him. He told me when he first saw me it was love at first sight. Now we r dating and we have been dating like for 3 or 4 months :)
