A conversation from bedtime:

• “Did you ever break a toy when you were a little boy?”
• Yes, honey, sometimes I did.  And my daddy was pretty good at fixing things, but we didn’t have a robot.
• “I have an idea!”
• Oh?  What’s that?
• “We’ll get a big box and a pulley and a rope and tie one end to your house when you were a little boy and pull on it and put the other end in my house and then you’ll have a robot when you’re a little boy!”
