Funny story... a few weeks back I bought him the Mandalorian Battle Pack ( ages 6 - 12 ). He could hardly wait to put it together. I promised that we would build it after I got a drink of water. I got side-tracked with a honey-do item... and didn't get back upstairs for fifteen minutes. When I returned, I found him playing with a finished speeder.
Dad: "Sorry... I'm back."
Patrick: "Vroooooom.... pew... pew..."
Dad: "Oh. It's finished. Did your brother help you?"
Dad: "Did your sister help you?"
Dad: "You put it together by yourself?"
Patrick: "Yep. WEEEEEEEE pew... pew... pew."
Dad: [ mouth wide open ] "How?"
Patrick: "Dad. I just followed the instructions."
