It's interesting that I seem to have a completely different set of expectations depending on whom I'm working with. With Moo I expect him to comprehend more easily because he has been learning for longer and conversely I expect less from Chaps because he is only just starting out. I'm guessing though that maybe I should expect to be surprised sometimes and not without reason. Chaps is 'uncluttered' whereas Moo has so much white noise buzzing about that my guess is that he is sometimes almost 'deaf' to my blabbering.
So it was frustrating (albeit enlightening) that Moo couldn't translate my aid for halt when ground driving at liberty when Chaps could even take the next step of staying front facing during this halt. Also interesting (although I'm not actually certain of it's meaning OR relevance as yet) that Moo gets unclipped in the school and goes roll and mooch for 2 minutes until he comes over to work whereas Chaps is 'with' me from the first second.
Note to self..just shut up around the horses, less truly is more or they will (like children) just stop listening!
