anyone know why ? does it really mean anything ??
I'd say it means about as much as the number of white feet telling you how reliable the horse is, the position of swirls on the neck telling you what his temperament is, the shape of the swirl on the forehead telling you how smart he is, and how far he rolls over telling you how much he'll bring at market.
It's all interesting bits of horse sense, with perhaps an element of correlation between physical attributes and mental/emotional tendencies, but take it with a large grain of salt. Just like people. I know some really laid-back redheads, some fantastically ditzy brunettes, and some scary smart blondes.
The one thing with the direction of the mane that I did hear that might be worth investigating is that, if the mane lays on one side for part of the length, and switches to lay on the other side for the rest of the length, that the neck could be out of alignment, "chiropractically." I forget where I heard that - not from a chiropractor, though. I can see that being possible, and if the neck is out of alignment that would definitely influence their posture and carriage.
Knowing Linda's "style," though, I'd expect it was more of a behavioral, emotional balance and carriage sort of thing, not a physical issue indicator.
I'll be nice now, pwomise...
