Be quiet or Stay quiet?

[Svetlova]

Já procurei aqui e não consegui a definição que procurava. Se uma pessoa gosta de agitar e a outra gosta de ficar mais quieta ou prefere ficar quieta, como posso falar " He likes to be quiet ou he likes to stay quiet?"

[PPAULO]

Could be that someone likes to hang out or socialize, while others like to be still (or it's an indoor person or even a recluse, likes to spend time at home), etc.

'Hang out' would suggest going out with one or a few friends, etc. With 'Socialize' I thought of a person being a "social butterfly/social person/outgoing person".
