They (do) that every Saturday. She isn't here, because she (is playing) football with Casey today. Mum (is going) to the shops (shop). She does it every Saturday morning. Dad is outside. He is (washing) the car. At the moment I (am listening) to the radio. They (are playing) one of my favourite records. I must go now. The doctor (is coming) upstairs hope you're well. See you.
