We seem to be most authentic when wrapping information we wish to communicate in humour. It can be a thought-out joke, or a haha or an emoji appended to an end of a pseudo-serious sentence, but ultimately there is some sort of truth or genuine feeling being communicated. Humour gives us permission to be honest and vulnerable, because it incorporates an insurance policy. If the information wrapped in a joke becomes too serious or offensive, we can always claim we were trying to be funny.
