It’s especially annoying on a ski hill.
If you’re going to stop and chat, get to the edge of the run, anywhere other than right below the shoulder of the hill where you can’t be seen. Don’t stop in the center of the hill, especially where the sudden change of pitch is going to hide you, i.e. where everyone is going to be aiming, full speed, without being able to see that you’re there.
Everything man-made has a function. It’s irritating when people can’t understand that their use of the thing is unnecessarily interfering with that function for everybody else.
