Mary Helps Grandpa

Mary helped Grandpa in the garage on Saturday.  Grandpa had 7 tires that he needed to store in the loft of his workshop.  The tires will be used in the boat making process.  Grandpa had a pulley system to lift the tires into the attic.  He showed Mary what to do and asked her if she had any questions.  Together, they moved 7 tires into the loft in about 20 minutes.  Mary lifted, hooked and pulled the tires.  Mary did her part independently and Grandpa did his part from the loft.  They made a great team.
