Apple needs to put a warning on their products:

Just joking (half joking at least.) It happens to all of us, but you can't save your baby every time. So far mine doesn't have any scratches since February...but I did knock it into a corner and it actually warped the whole body slightly near the Ethernet port. Luckily I had the strength to bend it back with my hands (I was surprised at how easy it was, but I am a bodybuilder 😉) so now you can't even tell.
Just go to a hypnotic therapist and try to have them make you forget the scratches are there.
