One time I was a little late arriving to a show, but not to the point I missed any classes, they hadn't even started yet and I was either in #5 or #8, and I was riding with my trainer because I had to get my horse in the trailer and she'd just take us since she had another horse to take, too. Well anyways, I got my horse out, and my aunt had brought our trailer since it had all the tack and my show clothes in it and such, so I got my horse out and took her over to the trailer and tied her up, then just jumped in the tack room of the trailer to change into my show shirt. I got in, closed the door, and after I was changing realized that I had locked myself in there. I had to call my mom, because thank god I had my cell phone on me because I usually don't at shows. My entire family laughed at me, but I ended up winning that class and being eligible for the grand/reserve grand champion class.
