Oliver

An Oliver is the most caring kind of person you'll ever meet. Sometimes he doesn't want to show, but he really cares about stuff. He's intelligent and extremely logically thinking. An Oliver could win every discussion about politics/society/science with his enormous broad knowledge, but he'd rather let people talk and get them to realize their wrong conclusions themselves by asking critical questions.
You can always rely on Oliver and giggle about his silly jokes.

He's such an Oliver, I'm seriously gonna rethink my arguments.
