mature folks (which aren't my friends).
I've been sport climbing for a while now, sort of, under an
instructor(s), and sometimes I see some people belaying perhaps the
wrong way, which may be (1) very serious mistake (not observed as of
now) or (2) mistake which MAY be potentially serious.
I don't know if I should just tell them the right way to do it --but
then they may not take it seriously since I'm not an instructor; or
if I should consult with the instructor to confirm that it's wrong,
then tell the instructor who has been making that mistake --but I may
get on the bad side of some people or may seem like some ass who likes
to make other people look bad/ backstabbing.
So...I'm always this indecisive. It sucks a lot.
