What is the sweetest Thing you ever did to your bf/gf?

I think its hard to say what is the sweetest thing I did to my girlfriend because our relationship itself seems sweet. But there were many moments which I think were sweet and girls love these sweet things. I mean things like when I made romantic atmosphere and we were just enjoying each other or when I wrote her some poem how much I love her.

I wrote a poem for him and it happens when he was so good to me so as I like to write a lot I decided to write a poem for him to tell him my feelings for him, he was and is so happy though when he reads it.

All the things I have done to my beau he considered it the sweetest thing. But what is the most sweetest thing I done for him, is I guess being on his side when he is down. Even if we are far apart, I eventually ride on the plane just to be with him even for just a day because I have work the next day.

Though i was far away from my boy friend, i turned up to go and meet him in last valentine day with him. He was very happy that i never was him that much before. he didn't believe that i was near him, he told me that he was not accepting me to come and meet him.
