Once I was traveling on a train to London. I was on a section for four people and there was a table between us. The man opposite to me had his briefcase on the table. There was no space on my side of the table at all. I was unhappy. I thought he thought that he owned the whole table. I had been reading a book about nonverbal (非语言的) communication so I took various papers out of my bag and put them on his case! When I did this he suddenly became angry and his eyes nearly popped out (突出)of his head. I had taken up his space! A few minutes later I took my papers off in order to read them. He immediately moved his case to his side of the table.
