I had something happen recently that definitely could have been bad, lol.
I was leading my mare back to her paddock. In order to get there, you have to walk through a gate, through a smaller, narrower paddock (we call it "the alley"), and through yet another gate. Another boarder's mare, Grandma, is 36 yo and spends most of the day in this alley slowly eating her mush, away from her pasturemate so she can be in peace. Now I've led Lilly through the narrow alley with Granny already with no issues, as this old girl is very laidback and generally only cares about her gruel.
So off I go...we are just within the gate, when Lilly stops and plunges her head into Granny's water bucket. Granny is on my left, about two/three feet from my shoulder...then Lilly, then the fence right next to her. Well, when I pulled Lill's head up, she sidestepped onto my toe (ow). As this is happening, Granny's pasturemate is walking over (she and Lilly are still having issues) and Lills leans even more weight onto my foot to avoid confrontation over the fence...keep in mind I can't really get out of her way because Granny has taken another step closer and I am now sandwiched between two horses. When I finally manage to push her off me, she backs up (faster than what is appropriate, due to the pasturemate's iminent arrival), and swings her butt into the fence, causing the gate to crash into her rear and stirring up a cacophony of rattling metal and hinges that would have had most horses running for their lives.
Yeah, I was basically preparing to die...stuck between two horses as I was with my Arabian having just backed rather hard into the noisy and retaliatory fence...but nothing happened. LOL Lilly just stood there with her ears slightly back when I was fully expecting her to freak out. All Granny did was back up a smidgeon, and the pasturemate had skipped off somewhere.
So as you can see...I am very fortunate.
Another "near-disaster" experience involved my very first riding lesson. My instructor and I were standing in the stall of my schoolhorse so he could show me how to put the halter on properly, when a tarp started flapping outside. Dear old Chalk freaked and reared up...my instructor backed me into the corner and threw his arm out in front of me as this massive hunter was having a conniption fit right in front of our noses...we were trapped and could have been seriously injured so easily...but then Chalk fell over on his back, halfway outside (luckily the door to his run was open!), and scrambled to his feet with nothing but a small cut on his leg. Thus continued the lesson.
Such a positive introduction to my first schoolhorse, lol.
