Fillin' the gap

Unlike most people, I love to be stuck waiting- that's when I can  do what I want to do- to draw at my leisure time. I was at ER with a family last night and the waiting game was taking forever. Coming unprepared, I didn't have anything to draw so I asked a nurse for a clean sheet of paper and a pen. And the game was on. I was happy and satisfied I was able to do these 3 caricatures until my phone died. I have to wait for the next morning to post this online.  

Imagine if I were not able to fill the gap of an empty time.
