Grammar: Dig

Lisa and Edward loved playing in the sand together. They were both four years old and they played with cars in the sandbox on Sunday. Lisa dug tunnels, and Edward dug up sand to make buildings with. They dug for hours in the afternoon and never got tired. Lisa dug through the sand very carefully so the tunnel would not collapse. Edward dug into the corner of the sandbox where the sand was moist. This was better for building with, he thought. Their mothers took pictures of them playing in the sandbox to show them how much they liked digging.
