8 or 9 y/o: we just got a computer, but I only got to use it while my mom was on the phone, & since we had AOL, I couldn't use the internet. so I doodled in Paint, but I hadn't realized I could resize the canvas, so I ended up doodling a *lot* of vertical banners for a *while*.
7 y/o: invited a boy from my class to come over after school to play. he said "no, you have chicken pox". I laughed and hand-waved away the fact that I didn't know what kind of food 'chicken pox' was by confidently saying "no I don't, but we can make some other kind of food!"
