Pissed at my school

Okay so I generally like my school, but I was SO angry today, but I'm kinda wondering if I have a right to be...I don't want to be brat and blame my failures on others

So my school shares their lot with a trailer drop off yard for Werner and Roehl. It's just a dirt plot of land and the students use the front part to practice backing, and the trailers get dumped in the back. Well today some idiots from Roehl put their trailers in our training spot. It matters because the training spot is paved nicely, flat and level. Since they parked there, we got stuck in the back in the deep mud.

I couldn't back in the mud! No one could! And I take my test next week, so I was so mad today was basically a day wasted. I couldn't even straight back once. It might as well been my first day again. I'm worried it's going to happen again and if I should complain...Am I being a baby for not being able to back up on uneven, hilly, and deep muddy terrain?

 

Yeah I thought so too...hopefully it won't be an issue tomorrow, but if it is, I want to throw a fit haha

 

Yeah I've never backed on asphalt before! Hopefully it'll make backing on the test easier...

 

Yeah I just wish I knew how to do it? In our normal situation I can do all the backin techniques with minimal help from the instructors at this point, but today was a disaster.
