While this one was napping yesterday Martin started asking me how everything works.
It started off like this: "why gas burns under our hood? I want you to teach me how a car works."
Seriously? What thee year old asks these kind of questions? Boy, am I glad I am an engineer. I am way more fit to answer these type of questions than playing dress up. :)
So, I pulled out a book that explains how various things work and we sat and looked at it for almost an hour. We learned about most of the parts of the human body and many different vehicles.
