While I was baking a cake,my cat was sleeping. When I saw him,he was playing volleyball. While they were sunbathing ,I was swimming in the sea. When he came into the classroom,the students were talking. While he was riding a bike,I was walking in the park. When the phone rang,I was having a shower. While she was tidying up her room,her brother was doing the washing up. When mother saw me,I was crossing the street. While you were watching a movie,I was studying. When he returned,we were waiting for him.
