best behavior

Polite and proper

Best behavior is conduct that is polite, proper, and carefully controlled—the version of yourself you present when it matters.

The phrase almost always appears with "on": The kids were on their best behavior for Grandma.

It implies effort and restraint, suggesting that less decorous conduct is the norm.
