For a while my little granddaughter was afraid to come down a slide like this, even though she really wanted to. We told her we’d be there to catch her and she’d be fine, but she’d just sit there clinging to the rail at the top, caught between fear and desire, until someone went up and backed her down the steps. And then finally one day she let go, and down she came, and she was fine.

I wish I could tell her that was the last time she’d ever find herself stuck in that place. I know it well myself.
