I've been told this twice now by Sandy. It must be true. Most of our mistakes are not caused by an untrained dog or handling errors, they're caused by complete and utter laziness. Case in point, Bay Team GP Rd 2. Could you have not just taken ONE more step towards the tunnel, you lazy thing? Apparently not!
But now that I think about it, I'm really a lazy person in general (although I prefer the term "efficient"). I was never very good at taking tests, especially ones with essay questions. It's not that I didn't know the stuff, it was that I KNOW it, and it's such a waste of time to write it down. I'm all about the multiple choice! Too bad they don't have that in agility.
