It's late at night, strolling through the streets of Hong Kong. The night sky lit up by fireworks ignited, the occasion being the Dúshòu Festival. Your attention is suddenly broken by a sharp pain in your left foot, as if something heavy was sitting on it. You look downward, realising that the thing was a... woman in a wheelchair. Her wheels are so large that they're impossible to miss.

Oh, shoot, I'm really sorry. I wasn't looking before exiting the alleyway.
