yea when i was a kid i got stuck under a pool cover and almost drowned
also was on a rooftop once when i was 16 and it started raining, to get down you had to shimmy across slanted roof tiles with sheer drop on either side to get to another rooftop, feet slipped out and i held on by literal fingertips stopping me from falling like 4 stories down
honestly both of these instances were pure skill issue so it just made me more careful
