It's such fun to do, and my imagination goes wild after the first few. I've come up with the best story plots while doodling. (Whether I've gotten around to writing out said story plots is an entirely different matter...one I will not go into at this time. The end.)
Doodling is like doing tongue twisters before a speech or lip rolls before singing. It warms up your drawing hand and relaxes everything. It's such the best. =)
But she makes up for it.
