At first I thought, 'kritzeln' was the appropriate translation for 'doodling', but when I had written it down once or twice, I remembered that 'kritzeln' is maybe more like 'scribbling'? But what is german for 'doodling', then? The internet says it is 'kritzeln', but gives 'kritzeln' also as the translation for 'scribbling'...doesn't seem right to me. Isn't scribbling different from doodling? Anyway, here is a doodle with a heart and the same word over and over.
