We laugh when things are funny. Right? Doesn’t everybody? Well, actually …
I was at a press conference in Ghana where one the speakers went far too long. The audience expressed its disapproval of the long speech with soft laughter when he opened a new chapter to his talk.
In another instance, a person was bringing greetings from one church to another, but it turned into a speech. A titter of laughter started running through the congregation showing disapproval with the amount of time the person was taking. The person bringing greetings even apologized when she heard the laughter.
I was in a vehicle belonging to an African and the air-conditioning was blowing on me in an uncomfortable way. I tried to change the direction of the vent, but we hit a bump and I ended up messing with the settings. The driver and owner of the vehicle thought that I had changed them on purpose and laughed lightly while looking at me disapprovingly and putting the settings back.
In Ghana and some other places in Africa, laughter sometimes means disapproval.
