Twilight Sparkle sends out a few letters and lessons on friendship to Princess Celestia, but soon enough finds that experiments done as a result of those lessons don't quite go according to plan. One backfired session of truth or dare leads to letters Twilight wishes she hadn't sent.

Except she did, at least in this story. Whoops! Maybe we can hope this never happens for real...

An older MLP story I wrote about a year back that I figured was as good a first thing to upload as any.
