During these Summer vacations a schoolmate who was not in my class went to Britain.  Before he left, his classmates and some of us who were accquainted with him had a B.B.Q on the beach.  When I arrived I saw that some people , who were not close friends of the departing person(person A), were playing mahjong.  Some others were playing bridge and A had nothing to do, besides it was A who had prepared the food.  Later when we wanted to talk and his classmates did not even have the decency to listen to him.  They only asked him a few questions half-heartedly and then they talked on their own.  Some of their conversation was against me and  another classmate.
