Yes I do believe in love at first sight, but I also believe that it is quite rare. Before I even knew my husbands name, I KNEW that I would marry him. He came into the place I worked looking for a job and when I saw him, it was like he was the only one in the room. My peripheral vision literally whited out, I saw nothing but him standing at the counter and I've never ever felt anything like that since. We just celebrated 22 years of marriage.
I like to think that it was due to a deeper 'sight' than visual appearance. He was and still is a handsome man, but I've seen cuter in my lifetime and 'looks' alone never stirred anything even remotely close to what I felt when I saw him.
