LMAO, I just had to post this video. I hadn't ridden Zierra in about two weeks, and with work and it getting dark so early my farm time was cut in half for awhile. She gets furious when I don't spend enough time with her - she wouldn't let me catch another horse until I opened the gate to let her out, where she promptly ran to the round pen. Shay-la was trimming Cinder and I brushed Zierra out, and she was harrasing me for quite awhile then gave up and decided to harrass Shay-la.
As for the "kissy face game", I swear she's not actually ticked. They play this game constantly and it's usually Zierra who instigates it, not Shay-la. She'll following Shay-la around the pasture if she plays it with her and then walks away. She's just crazy like her owner
