Not really "fell in love" but the first time I felt something kinda strong for someone was when I was 14. There was this boy who lived in the same quarter as I. I was just waiting for the bus, and he passed by. It was the first time I saw him and I was like "hmmm" but it was when he passed by for the second time that I felt extremely attracted to him, and from that moment on I just kept on stalking him from far. In only managed to see him at the bus stop but actually we didn't wait in the same stop cause he was going to one way and I was going to the other so I was always stalking him from the other side of the street. Looking back now it was very embarassing.
When I discovered his name, randomly, by a friend of mine who knew him, I looked for him on social media and I actually sent him a friend request and he accepted. Damn I was so brave back then

Now I don't even send my crushes friend requests.
I never got to talk to him personally though, once I was in a bus and he was there too (he was actually sat in front of me and he looked back and recognized me), and he started talking about a girl he was hooking up with. That was kinda when I realised he wasn't for me and I was just having false hope. Bless!
I think I saw him this year, in college. I'm not sure though, he's different now.
