Well that's a great start!!!
My little moments are those when kids have come over after a flight to give me hug. People telling how a great flight it was.
On one occasion we had this businessman from States. We were three different nationalities on board and he spoke with each of us in our languages. A truly amazing man, and at the end he offered me a bottle of some fantastic hungarian wine.
On other occasion i had this swedish woman going out on vacations who was terribly scared of flying, i spent quite a lot of time talking to her. She got off very happy. I had her on her flight back home as well, and when she saw me greeting the pax, she hugged me and told me how much talking with me has helped her through her long houl flights and how happy she was to see me again.
