A real person is one that is "genuine" and "earthy". Real people do not take part in hipocrisy and lies in order to undermine their opponents. Real people often keep friendly relationships regardless of their benefits or non-benefits from it. In the end, a real person will stand by you, even when the fun is gone and life gets rough.
When my house burned down all my friends wouldn't let me stay with them, but Tony would......he's real.
