With Pinkie Pie's birthday the next morning, Rainbow Dash needs to get to bed. However, the feelings for Pinkie Pie, that she has been repressing are starting to force their way out. Rainbow Dash can't sleep, she can't wish her tears away, she can't settle her stomach, she can't miss the party, and she has to get the feelings out. The poor distressed mare decides to write out a letter. A letter Pinkie Pie would not expect, but still understand. It would save her from Pinkie Pie seeing her nervous, blushing, and maybe crying, and yet she can still poor her heart out. However… That doesn't mean she won't be rejected.
