It may be the polite thing to do but it's certainly not the easiest. I really enjoyed drawing the lady cut in so quickly in the second panel. She must be a pro. IF YOU'RE LOVING MY COMIC, PLEASE CLICK HERE AND LIKE MY FACEBOOK FAN PAGE!
I'm always surprised with how normal it is for elderly women in Japan to cut in front of you in line. It took some getting used to at first but it seems like people just respect the fact that they've earned the right to do what they want. Have you experienced this before?
