I remember once I got my girlfriend (now ex) a flower from the park when we were walking through it, then she lost it and got upset because she loved the flower and wanted to keep it. Anyway once I walked her home I went to the park again and picked another one of those flowers. The next day I got to school and went up to her and pulled the flower out my sleeve, her eyes instantly lit up.
That was one of the highlights of that year, just that one reaction.
