This is Buffi and her buddy Bonfire during a mutual grooming session.  

I've had Bonfire since he was 2 months old (he wasn't weaned that early, but I spent 3 months working with him).  By the time he was weaned, he was leading, picking up his feet for cleaning and trimming, standing tied for grooming, and doing all the things a horse has to know.  He's such a sweetie, and a smartie, too.  He's my resident horsedini.  I've had to put a carabiner snap on each stall to keep him from getting out and letting everyone else out, too.  He even taught the donkey how to open them, so now I have TWO escape artists.  (sigh)
