Common sense isn't so common

(phrase / life observation / savage truth)

A brutally honest way to say that just because something seems obvious, most people will still find a way to mess it up. Perfect for moments when humanity disappoints you, usually in public or online.

Used when:

Someone does something completely avoidable or facepalm-worthy.

You realize society collectively skipped the “how to adult” manual.

You want to sound smart while judging idiots.

Meaning: Humans often act in ways that defy logic, and that’s on them.

Synonyms: “Apparently, this is optional,” “Logic is rare,” “Humanity, why?”
Examples of contexts in which common sense isn't so common:

Coworker: “I put metal in the microwave.”
You: “Common sense isn’t so common.”

Friend: “I just walked into traffic because I was texting.”
You: “Common sense isn’t so common.”

dozen't make sense

What you'd say regarding da fact dat an 18-pack of eggs sometimes costs more than half-again-as-much as a box of 12.
One generally expects dat buying a larger "bulk" package of a certain item would automatically make da per-piece price lower, so it dozen't make sense to charge an extra 57% for an 18-pack of eggs.
