Coming from the opposite direction, there is a theory of humor that basically says that what humans find funny are things that are not usually ok made ok.

This is also known and the "benign-violation theory"[1]. Things are funny when they should offend or violate (even at some simplistic level) but don't. Someone slips and falls? It can be funny as long as we judge them to be mostly unharmed.

Back into your context, and to reinforce what you said: it's possible you're instinctively trying to communicate that, as dry as the communication is, you're trying to add levity to the subject matter.
