Face it Daddy, I'm an artist. I have a right to get a little hot-tempered when things aren't going in the creative direction I want.
When I have a creative meeting with Daddy where he tries to steer things away from my vision I have to rough him up a bit.
If all else fails I give him the Pachycephalosaurus Head-Butt.
Sorry Daddy, a true artist doesn't compromise. Think about what the Sistine Chapel would have looked like if Michelangelo had played nice!
