I readily admit that I wouldn't know a good hole, seam or slot if I were to see it, but I still like standing, casting and thinking more than I like moving around a lot. I don't think I pick good spots to stand either, as everyone else heads up or downstream and catches fish while I stand and think. Still, the very rudest thing I have ever seen while angling was some jerk that was wading downstream, casting every few feet as he traveled. I was out in the river more than far enough for him to politely go behind me, say hi, and keep going. What did he do instead? He just kept on coming, walked about three feet away in front of me as he passed, and then cast literally right over my line so that I had to reel in fast before it tangled with his. I know I had left my Invisibility Cloak at home, therefore the guy was just a plain a--.
I didn't say anything to this man, as nothing I could say would really capture how pissed off and insulted I was that another angler could be so rude. I have no problem at all "sharing" a spot with someone, but when I arrive at the water I ask anyone within 50' if it is okay for me to work near them if they are there first. I will always believe that anyone who asks with courtesy will get whatever they need from me. Barging ones way through a situation will get them nothing.
