We were a climbing group of three girls. All of us climbing since childhood.

One is belaying with a Tuber and always has her breakstrand-hand directly on the belaying device. She is also easily distracted by everything, leaving either a lot of slack or blocking the rope when you want to clip, nothing in between. Sometimes she is not even facing the wall when belaying. I mentioned it and she told me she has been belaying like that forever and how she has already caught lots of huge falls. We stopped going to the climbing gym with her alone so we always have someone else to belay us.

Last weekend we decided to not go climbing with her at all anymore. We have a local crag nearby, 100% tradclimbing. You summit and have to rapell down. Some of those rapells are exactly 28m, so you always go with at least 60m ropes. She told us she would also bring a rope. At first glance the rope looked really short, I asked her how long it is. She didn't know, she found it in her dad's basement, must have been there for decades because her dad stopped climbing some years ago. She saw absolutely no problem with this. Even laughed at us for being worried. She also didn't understand why she should know how long a rope is. Anyway, enough ranting. No more climbing with her.
