out of character

His close friend Lucy Hatton said his disappearance was "really, really out of character" but that he had not "been in quite the right head space" recently.

Everyone who knows me, knows that would be out of character for me - it's not my style.

That was weird to me and out of character for him.

"We noticed that his personality was different, he was becoming aggressive and acting out of character. I wish I had acted on those warning signs."

Avon and Somerset Police say they were "extremely worried" for Mr Piovesana, as it was "out of character for him to be missing".
