I want to lose some weight !   So do I !   I have a yoga class tomorrow . Do you want to come with me ?   No , it's too expensive for me . I've decided to take some exercises on my own .   What are you going to do ?   Run around the track . In the morning I run for an hour , and in the afternoon I run around the building .   Good , I am sure it will work if you can persist .   I hope so . Would you like to join me ?
