Подставте в правильном времени: I (arrive) at Sam's party at 9.30 p.m. Lots of people (dance) in the living room. I (go)

I arrived at Sam\'s party at 9.30 p.m. Lots of people were dancing in the living room. I went into the kitchen. Mike was there. He was standing in front of the fridge. He was eating a pizza. I said hello, but he didn\'t hear me. I don\'t think he had listened. I left the kitchen and walked into the hall. Linda was sitting on the stairs. She was holding her hands. Her shoulders were shaking, but she wasn\'t crying. She was laughing!
