doo·dle ˈ/ do͞odl /
verb:
scribble absentmindedly "he was only doodling in the margin"
noun:
a rough drawing made absentmindedlyThe chair was stamped (Claudine Hellmuth) and then I drew the table. The globe and the hot air balloon were stamped (Tim Holtz Tiny Things); the books, shelves, windows, wall and floor were drawn.
I would argue that drawing and doodling are not the same. But if you consider the definition, I guess this was absentminded in the sense that I have no idea where the idea came from but once I decided to add the books, I thought the quote by Lemony Snicket was a good fit.
