Crayons 

crayons mean I'm not afraid to misspel words or use grammar bad in a post even though people would laugh or hate it. You cannot erase a crayon and you can't get fine details with them, but if you really look at a picture a child draws then you'll see what they think and gain far more detail than u would out of a perfect drawing of a portrait. It shows you their creativity and what they make out of nothing.
