Octavia Melody is the most difficult part of Symphony's day. Everypony hangs on her every word, worships the ground she walks on, and generally makes a big fuss over little things even when, in Symphony's expert opinion, she got that 3rd G flat wrong in the second movement.

Thankfully, Symphony has a sister; a very observant sister who's intent on coaxing Symphony's woes from her in the least embarrassing way possible.

No matter how embarrassing the least embarrassing way is.

A story designed, or at least intended, to cause warm feelings without the requirement to set fire to your house. You're welcome.
