They are curious things, Twilight, made by ponies in passing, yet providing ever so much information to those that know how to read them. Some leave a big impact, like mine for example, but that does not mean that others haven’t left their own marks, small though they may be.

What most ponies do not understand is that the size of the hoofprint they make isn’t static. It’s size depends wholly on the viewer. A mare who has never made the tiniest mark on history, could have the most profound impact on the foal to whom she is a mother.
