A little lengthy , but from The Circle of F r i e ndscircleoffriendschapter 1 GR link Dusky sighed , her ears drooping a bit . I wish I understood better , Ladyship . The princess smiled . You will . She brushed a reassuring hoof over the girl ' s mane . Soon , my most faithful student , the time will come when I send you out into the world to learn its ways . In that time , I believe , you will discover many great and wonderful truths about friendship . But allow me to give you the first lesson now . It is this that all things pass in the course of time , that forever does not exist . That every Hello contains within itself the echoes of its own Goodbye . That for every person you come to know in your journey through life , no matter how long you know them , there will always come a day when you will see them for the last time . And yet . And yet . it is all worth it . The princess looked back up at the stars , the light from the moon reflecting in her eyes . The time between Hello and Goodbye , if you fill it properly , will sustain you through all your days . Every shared moment , every laugh , every precious sliver of time spent with someone you care for is a treasure , to be kept safe forever .
