Taylor Swift is the world’s best friend, if you didn’t already know, and this weekend she celebrated childhood best friend Abigail Anderson’s 25th birthday. Swift, in top best best-friend form, arranged a WTF-NO-WAY-RUFK-AHHH kind of surprise by way of a performance from Dashboard Confessional’s Chris Carrabba.

During the party, Swift called up Carraba, Anderson’s favorite musician, to sing “Hands Down.” Other Swift bestie, Paramore’s Hayley Williams, joined in, and the world became a better, more emo place.
