高分语料：It was when I was travelling with my cousin to Chandigarh on a bus.It was around a month ago.There were around 50 passengers in the bus and of all age groups.People were doing different activities- some were talking to each other, a few were reading, children were busy playing games on the mobile phones and some were sleeping.After about half an hour into the journey, a passenger sitting in the middle of the bus started talking on the phone.He had a very loud voice and I could hear him even though I was sitting in one of the front seats.I couldn’t help hearing his conversation because of his loud voice.Apparently he was talking to his wife.From his conversation it seemed that he had forgotten their wedding anniversary.He was apologizing profusely to his wife and was saying that he was ready to buy her anything she wished for.
