Tom enjoyed going to the movies. He especially liked seeing movies made from stories he had read in the books. He went at least once a week. He liked to sit in the same seat, but sometimes when the theater was full, this was not possible. He had to sit wherever there was an empty seat.

It seemed to be watching the movie with interest, but from time to time it would turn to the man and bark quietly in his ear. The man would just nod, and the dog would turn back to watch the movie. Sometimes when something funny happened in the movie, the clog barked quite loudly and wagged(摆动) its tail. Tom sat behind the man and his dog for a long time without saying anything.
