If I have had a scary moment, it's been on reflection and way after the fact.
It might just be me but incidents have occurred, I've dealt with them, experienced the outcome, or just shrugged it off.
I can't ever feel scared, as such, apart from one incident ...
For reasons that are long and drawn out piffle, I used to climb the walls and roofs of my school. An urban climber, if you will, before parkour or exploration was a thing.
One cold and frosty night, I lost my grip on a roof peak and slowly slid down the clay tiles towards a three-story drop. I didn't scrabble - habit because I knew I wasn't meant to be there? - but glanced down for finger-holds etc. Nothing. Luckily, it was a slow process and I had a minute to think ... I came to the edge, and jammed my toes of both feet into the rain gutter! No probs!
Taking deep breaths, I looked around, assessed a way to get to a gable and edged my way back, to retrace my upward route and back into my room. It was then that I realised how close to plunging to my death.
