I've never been a fan of hunting. I know my meat doesn't come from the Turkey/Chicken/Beef fairy, but I have no desire to hunt down and kill my own dinner. ^_^;
But oddly enough, I think it would be kind of cool to go fishing and catch my own dinner. You would think that 9+ years of caring for bettas would turn me off from eating fish, but so far I still like tuna, salmon, and tilapia.
As for the OP...isn't that the point? I thought the reason for teaching is to help your student reach heights you could only see in the distance. (Yes, yes, I know that's sappy) I say take losing as a compliment. Either you are really, really good at teaching people how to shoot your your brother's a natural. I see either case as win-win. :)
