Hi again, All!
AnrewPL, we got them too; 'em as _talks_ about it, and 'em as just _does_ it. Some crossover, but not too much; The Doers will cheerfully give advice if asked, but rarely offer it otherwise, preferring to let them (as Whisperbaby suggests) "figger it out on their own". We learn best thru our mistakes in any event. (That is if we survive them :-)
Kind of off topic, but for your consideration I would like to offer one thought: Horses are individuals, just like us, and really need to be approached as such. What might work great for one could be a total disaster for his stablemate. For best results, keep trying different things until you find the one your buddy likes best. You'll know.
