Spot on. They never hold the door for you. Walking in the MTR is a hazard because these local zombies can’t walk without staring at their phone so they wind up smacking into me all the time. I got to the point I dodgeball and just slam my way into them with no “excuse me” to try to teach them life doesn’t exist on an iPhone. OMG thr language. I’m not sure which is worse Cantonese or putonghua but my god the way they talk gives me a migraine. Their are only two levels of volume here, OFF and EXTREME. Yes, they are extremely non spatial oriented, there is no one else in the universe except them.
