So what is a homeschooler to do when his teacher (mom) has to go into San Francisco for the day for a doctor's appointment? He goes to work with Dad! Yep, Joshua spent most of the day at Dad's office finding out what David does all day. However, most of Joshua's time was spent in the shop, not on the computer doing any of the design work. He was a great help as he prepared parts for a prototype.
If you have to go to work with your Dad, a toy company is a pretty fun place to spend the day!
