The happiest moment in my life is, no doubt, when my fiance asked me to marry him. It all went like so:

I was just leaving work and my fiance(ilovediana on here) came to pick me up. I had a horrible day and I told him all about it before we got into the car. He told me he wanted to take a walk along the riverfront with me (i work near a riverfront area), and I agreed. It was a beautiful night and the reflection of the lights of the city on the river looked beautiful. We just walked and talked for about an hour. When we got to the end of the "commercial" part of the riverfront, he took me to a secluded area on the grass near the water. I asked him what he was doing and then he got on his knee...
I started to cry and hugged him. We just held eachother for a while. Ah! I'm getting choked up just thinking about that night! I'm not sure if this sounds very romantic, but it was! One of those "had to be there" things to understand.
