Building a deck<br>Shirley wanted to add a deck to the back of her house. She asked all of her friends to come over and help. In exchange she was going to have a cook-out for them. She bought all the materials for the day. However it rained and the deck was not built.
The rain made them have to change plans.
Because of the rain they changed their plans and didn't build the deck.
