one of my happiest things

Hi,everyone!!
I wanna tell you the positive thing for me happened during last weekend.
It happened when I was working for part-time jobs at Starbucks coffee in the airport.
One of our customers looked me. I noticed that and I walked to him.
I know that He was a foreigner. So I talked to him "Hi,may I help you?"
Then he said to me, "You have a pretty cheaks like a marshmallow!!"
I was very happy to hear that!!
I explained that the food which he was eating was very popular in Japan and we were talking for a little.
I think my English isn't good for foreigners but  I wanna talk with many many customers from foreign countries.  Because I like talking with people and I like also looking their smile!!
