I tip my hat to you for getting your kid involved. I have a nine-year old nephew, and I get him out in the woods whenever I can, if his dad doesn't beat me to the punch.

That said, please, please, do the world a favor. That kid is only nine so he can be taught. Please wash his mouth out with soap every time his says, "eh". Do that so if he ever comes to America people don't roll around on the ground and point at him while he talks, eh? Arggh, now I said it! I'm going for the soap. That's absolutely the most irritating expression in the nonlanguage.
