Is when I go out to feed and my Arabian gelding Mister, WHO,WHO's at me. and for those who don't know what a who who is. well its kind of hard to explain, but to me that's what it sounds like he is say, WHO who who. My fiance, when we had just started dating, He didn't know what the big attration was with me and my horse, He is not a horse person (yet). He Says What is a Who Who? And when I describe the way Mister acts when I feed him, He always when I am out in the pasture or he sees me, he always greets me with a who who. So when i finally got him to come to the house and meet my horse, he learned big time what a who who was. We now live together with our boys and my horses, and now he takes pleasure in going and feeding mister just so he gets who who'd at. He loves it. He comes in and tells me, mister who who'd at me. He even bought his first horse, he bought her for me. She is a red line back dunn. and a very beautiful horse she is and a very spoiled horse she is. Now we are one big happy family with 2 beautiful baby boys and 4 horses.
