Yesterday I was speaking with my son about Dragons. I told him that dragons will eat people but mostly they fly around and pick up cows and sheep that are easily found in the fields.
And the fire they breathe? Well, that comes from eating coal, which they like to do. After eating coal, they create stomach gases that they blow out, but to light it, they make a spark with their teeth.
It really is amazing how easy it is to answer a 5-year old's questions if you put your mind to it.
