Did you ever have someone you cared about very much but they let you down. And because you expected so much of them..
... you found you couldn't explain to them what they did that hurt you because you expected them to always be perfect? You had them on a pedestal "up here", when in fact they were just human "down here" and make mistakes like everyone else.
Some people put others in their lives on pedestals. They think so much of them they treat them as if they are above human frailties, but that's so unfair because it leaves them with no wiggle room if they make a mistake.
