Last year I took my friend up to Mountaineers Dome to teach him how to place pro, do some mock leads etc. Besides us there were just two other guys doing some easy leads.
About an hour later a couple rolls in with their three kids. They are all noisy as hell, including the "father". He walks right up to us and says "I guess we've ruined your quiet day, ha ha". He then proceeded to set up a top rope, and make as much noise and be as obnoxious as possible with his kids. To be honest, I don't think the kids made any noise at all by comparison to this total fucking jackass. We finished the pitch we were on and moved up the hill to the easy 5.2 and 5.6 cracks up high just to get away from this asshole.
