I remember back in middle school where I drew this stick figure obstacle course in my notebook, and my teacher caught me drawing instead of some lab thing (even though I was already done), so she took it away from me and said that she would give it back if I told my parents what I've done, or wait til the end of the year, of course I wait til the end of the year, and turns out she lost it. Now I just throw my sketches anywhere now =/
But the distraction issue is me all over lol. For some reason, I become a perfectionist at home, and erase every 5 seconds which makes me hate the art later on, unlike in school where I would rather draw then hear my teacher ramble on for 80 mins about nothing.
also, since I have an audience, I show off a little and I'm just more into my sketch.
