No but really…
There are certain words that you just can’t say angrily.
Even if you manage the tone…after an arduous (murderous!?) day…you can’t possibly mean “bubbles” as angrily as you *try* saying it.
Oh yes, little things CAN diffuse stress – you mustn’t underestimate the power of absurdity and silliness!
No one will know that when you leave the room for a moment it’s because you are going somewhere where you can *attempt* angrily spewing the word “bubbles” (knowing full well, of course, that you CAN’T, and that you will be returning to your meeting with a giggle in your step.)
