Dear Princess Celestia,
My granny always told me you could never really know a pony just by looking at them. Take my family for example; so many ponies write us off because they think we're not up to their standards. What they don't realize is that we just don't say nothing because we've got nothing to say, and if we do it won't be nice so we hold our tongues. All right, maybe that's just me. But you catch my drift.
I've learned being smarter than everypony doesn't mean you always know what you're doing. That just because you're wearing a smile doesn't mean you're not hurting on the inside. That just because you like designer clothes and fancy jewels doesn't mean you don't want to have fun just like everypony else. And that ponies can still surprise you no matter how well you think you know them. But I think the most important thing I've learned about friendship is that it takes work. You can't call a pony your friend just because you know each other's names, you have to be there for one another to talk, to listen, and to support.
In trying to help my sister and her friends out I've learned a lot more about friendship than I knew before and I think I learned a few things about myself along the way. As long as you're open to new experiences, sometimes with ponies you think you won't get along with at all, you just never know when a new friend might come along.
