Pinky Promise?
Ah, yes, the trusted pinky promise. There’s nothing that ties a sacred grade-school vow as a pinky promise. Sadly, in our adult years, the trustworthiness of pinky promises fades, and we’re left relying on signing contracts with others to ensure that we make good on our promises.
The world would be a much better place if pinky promises were binding. We recall that one episode of Community where Professor Kane upholds the pinky promise Star Burns made with the study group. In the end, it worked out for everyone. Everyone except Star Burns, that is, who died horribly when his lab exploded.
