I didn't say or mean that everyone used a rope halter for all occasions on every horse, sheesh. Of COURSE there are exceptions and instances where one is better over the other. When MY HORSE is working, he's in a rope halter. When he's in a trailer or on a "break day", he's in a flat halter.
I'm very aware that every time I handle my horse he is learning something. I never said nor implied that a "break day" means he can do whatever he wants. I said that there's no training involved, as in, I'm not making demands of him. I'm not asking him to bend this way, or lift his back or stop doing a giraffe impression. All he has to do is have good manners - bad manners are corrected immediately, break day or not. I do consider it a "break day" when the only expectation I have of him is to have good manners. My horse will certainly try to test me on occasion, in very small ways, and they are all corrected immediately - regardless of day.
