My gelding Mellow has completely earned his name today.
When I got him, he was hard to catch, and wouldn't let you touch his back feet. Now he lets me walk up to him and pick up all his feet out in the pasture without being tied-- that is, of course, unless I have his arch nemesis, the fly spray. He won't stand still for it at all unless he's haltered. If I so much as open the gate holding the fly spray, he puts himself at the other end of the pasture and stays out of arms reach.
I also have an 18 month old son who LOVES the horses. He loves walking up to them and patting them all over. My mare I have to be careful about because she just plain doesn't care what's around her and will walk through anything, even me (she's a spoiled rotten pasture ornament that pretty much does whatever she wants). Mellow, however, will usually stand still while being patted, and while I don't think he'd ever move while my son is around his feet I never take the chance.
Well, today my son found the spray bottle and-- being a very smart little lad-- proceeded to head for the nearest horse to "spray" them. The nearest horse happened to be Mellow. I followed close behind, and stood there in shock as Mellow let his little toddler with a spray bottle half his size come waddling up and tap him repeatedly in the stomach with the end of the spray bottle. Then my son moved around to the front, and tapped him several times in the chest. Mellow never moved a muscle, and in fact didn't look concerned at all.
Mellow has certainly moved up the line to "favorite horse" at my house
