Expensive sketchbooks are made for scribbling, or should be
Dad and Zoey like to draw things...mostly scribbly, scratchy, indiscernible things that consume large quantities of quality sketchbook paper. Dad doesn't care 'cause he loves doing it, and Zoey doesn't care either 'cause she loves doing it too, so no one cares why Dad doesn't just grab scrap paper and scribble away on it rather than the good stuff.
"Even thirteen month olds need to feel like an artist," he says, "especially thirteen month olds."
No one believes his @#$% but it's cute and sweet and he paid for the damn paper in the first place so who cares?
