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.”

Internet comment section: literally anything ever.

Queen of common sense

A friend who tries to explain to you the strange behavior of the male species especially those particular male species that you have been flirting with and have a crush on. They are very sensible which is annoying and calming at the same time because lets face it-over-thinking stuff is tiresome.

Girlfriend-Queen of common sense.
