Cheerilee's Garden(车厘子的花园）Part.1(27)

But that wasn't true; the real reason was the one question constantly on Cheerilee’s mind: Can a Cutie Mark be mistaken? Is it possible that I never was as good at teaching as I thought I was? That I simply had easy foals and fillies to work with before? Or if a Cutie Mark is accurate at the time it manifests, can it perhaps grow inaccurate over time?
These questions and many more like it slowly pushed Cheerilee down into an all-encompassing feel of depression. She found her patience wearing increasingly thin and lost faith in herself more and more. It became hard to get up in the morning, and harder still to bring herself to return to the classroom where she knew they would be waiting, to turn another day into a living hell.
