be oneself(redirected from be themselves)

1. Act in one's usual fashion; be in one's normal physical or mental state. For example, Peter's finally recovered from the accident and is himself again, or I was completely distracted; I just wasn't myself.
2. Act without pretense; be unaffected, sincere. For example, I really enjoy their company because I can be myself with them.
