This two-second voice clip pairs an upbeat claim that the day was the best ever with a flat, dismissive 'meh' that takes it straight back. The contrast makes it land as dry, underwhelmed sarcasm rather than real excitement, the sound of a plan going wrong just as it was supposed to peak. It suits a small letdown best, when the moment was almost good and then quietly was not.
