The rational approach to German anger
I think Germans on the whole are not aggressive people, and being English I say this with appreciation. Today on the way home I saw a man hitting a crosswalk button in frustration at it having not let him cross the road in time, with an empty plastic bottle and shouting. But shouting something hilariously typical here..
A very common way a German will vocalise their incredulous displeasure at another's incompetence is to loudly say hello (hallo), just in a slightly stupider voice; ha-lohh!
It’s really quite limp and a wasted opportunity for some really good words but also hilarious and sort of comforting.
