The great thing about not being able to draw is that you don't get upset when your artwork is... Well, I was going to say "destroyed," but I think "collaborated" is closer to what I was thinking. Hm. No, still not quite right. How about: "Collaborated all over." Yeah, that's better. If you can't draw, you don't get mad when someone collaborates all over your work.
This was an attempt to paint a house while my son collaborated on it. It doesn't bother me much at all that my work is so collaborated. Certainly, it bothers me more when he collaborates on my laptop with his crayons.
