Here's a little story to ease your guilt.
I have a 16 foot wide garage door. I wished to remove the loader in the garage but I didn't want to put it in the middle of the place and monopolize all the available space so I dropped the loader on the left side (when you're facing the garage from outside) very close to the left door frame. At that moment, the tractor was only equipped with the loader.
I don't remember exactly what I did afterward but the important point to note is, I had the mid-mount mower on when I decided to put the loader back on. So there I was approching the loader when suddenly I heard and sensed a little shock. I looked down at the left door frame and realized that my beautiful mower had gouged a nice groove in the aluminum capping the frame. The shock wasn't violent, it didn't break the aluminum but gouged it a bit and left a nice orange stripe.
I was mad about me that day especially about the fact that I'd changed that piece of aluminum a year ago because the previous owner damaged it (I don't know how though). So the story continues...
I changed some doors around the house last summer and the delivery guys were talking to me while unloading the doors in the garage. One of the guys noticed the orange stripe on (or should I say "in") the left door frame. He asked me what happened and I told him the story, not without a little bit of shame of course. And you know what the guy said (he was kidding me of course but I felt very stupid at that moment)? Wow, you have a 16 foot wide garage door, it wasn't wide enough?
The point is... those things happen.
