Zazen's first day

It's been awhile! Either raining and muddy or I've been working on the gorgeous days, so I'm going to try to do better with updates from now on.
Starting from the beginning: Zazen arrived about 9:00 one night, yelling to the other horses and whirling around. I chalked it up to unfamiliar environment and having been shuffled around the last few weeks (remember that "trainer"?). His then owner told me to try him out, he thought the horse would be right up my alley, since I have a special spot for Arabs. Ms. Trainer told him that the horse was "one of the quietest horses she'd ever been on" and she "rode him in a halter". I settled him in the round pen with hay and water and let him hang out until the next day.
Day One Of The Journey: I took a book into the round pen and sat down to read. Zazen was not that interested in checking me out; in fact, he really didn't register anything. His eye looked dead. Should have been red flag #1, but I was trusting the report from Ms. Trainer. I approached him and haltered him, he wasn't relaxed at all with it. I saddled him and tried to bridle him; he slammed his head into me. (Hmmm, guess same reaction with trainer; that's why she said she rode him in a halter?) He was a very tight horse at this point; in hindsight, he was telling me he was not okay, but I still was relying on her calling him "a quiet horse", and thought he was just very sensitive to the abrupt changes. I was trusting my friend that this horse was broke- hah! I very quietly stepped up on him; and he very quickly put me on the ground! It finally dawned on me that Ms. Trainer had lied through her teeth to his owner. This horse was not broke at all- his reactions were panicked and explosive.
I left him in the round pen and called his owner, who at first thought I was lying to him, then finally came over to see what I was talking about. After seeing how his horse was, he left. Zazen's papers were left in my door several days later, and I haven't seen my friend(?) again. Hmmmmm.........I guess I'll never know what the real story is, but the result is I ended up with a very messed up horse!
