Twilight Sparkle has a lot on her chest that she wants to get off. She knows about the time old practice of pretending to write a letter to the pony bothering you and not sending it, but that's not enough. Frustrated, she invents a system where her letter gets sent to a creature from another dimension. She feels gratification from actually sending something and there's no way some creature from another universe could know her language. As it turns out, the other mares have complaints too, and Twilight is more than happy to help her friends!

Flash Sentry is a normal high school student who somehow keeps getting magic letters full of some REALLY messed up stuff...
