Anyway, for those of you who don't understand what's going on...
It's filly Lyra's birthday and her party is being thrown at her parents' estate/mansion (probably in Canterlot). Unfortunately for Lyra, the party mainly consists of her parents' socialite friends talking with said parents and being pretty boring.
Cut to filly BonBon, Lyra's best friend in the world, arriving to the party with a gift in-hoof. Now, BonBon's family isn't all that rich compared with Lyra's and naturally has a small gift. When the cream-coated filly finds her unicorn friend, she runs to her, only to find Lyra distracted by what could possibly be the greatest gift ever!
So, BonBon feels sad and dejected, since her gift for Lyra is small fries compared to what Lyra is getting and decides to leave. Lyra notices her sad friend leaving and decides to set things right.
Lyra and BonBon, along with other ponies, were created by Lauren Faust and belong to Hasbro.
EDIT: I had accidentallied Lyra's missing freckles in the last panels of the comic.
