Please help me correct the following paragraph. Thanks!
Jack, Mary, and their parents had a family day on Saturday. They decided to stay at home because it was raining outside. It was 3:30 p.m., Jack was eating some popcorn and watching his favorite TV program while Mary was sitting on the sofa and reading a nice book. Their parents were playing cards, eating pizza and drinking a glass of juice. They could not play outdoors, but they had a good time. They were very happy.
