When I went to a convinience store this afternoon, what I've never experienced happened.  One foreigner man walked into the store and got some stuff and moved to the counter as he didn't realized there was a line waiting for the payment. (I guess it was hard to find the line from where he was)  The clerk told him "there is a line over there."  Then I was on a head of the line, and not in hurry, so I told to the clerk that I don't care about being after him.  Then the man approached, held out his hand, smiled, and said "Grazie!!"  I took his hand and then we shook hands.  I felt so heartwarming.  I can say it was a nice day today only with that event.
