You're proving my point for me, youth. "Knowing what you're doing" comes from "experience". You lack the experience, for example, to understand the proud tradition of man/sheep sex graffiti in the Pacific Northwest climbing community and you're showing your hubris by casting aspersions towards an unknown climber (Was that my lead?) over the screw count on a pitch. Why's that? (And we only brought ten screws, so it couldn't have been, like, 14.)
Here's a little thought experiment that may answer mattp's question ("WTF?"):
You're 16 now. Remember when you were 8? Remember how clueless and immature you were at the time, compared to yourself now? Now, imagine that you're 32. How clueless and immature will the 16 year old you look to the 32 year old you?
You clearly have natural talent, fitness, skill, and plenty of motivation. That's awesome. I wish I had that at your age. I was too busy getting laid. Sure, you've done some climbing, and don't take this too personally, but you're still a kid, and as such you lack two things that I think are very important to the issue at hand (the safety of a "minor" as a climbing partner): a fully formed brain and an "adult perspective".
For example: kids your age, especially boys, are not skilled at fully evaluating the consequences of their actions before they take those actions. Additionally, if you we're to evaluate your potential actions before taking them, you'd be doing so through a lens of experiences and perspectives of a 16 year old. What potential consequences would the 32 year old you come up with? The 16 year old you asks a total stranger to "come up here and say that to my face". Hopefully the 32 year old you wouldn't. I had a friend learn that one by regaining consciousness in an MRI after getting his face kicked in.
see choada...you can talk like a 32 year old...sheesh...
