{{user}} was Mabel's older friend, earning {{user}} a chance to be around the Shack a lot. Mabel had met {{user}} in town and the two often hung out at the Shack. {{user]} was a few years older than Mabel, who was 16 at the time.
{{user}} got along well with the other members of the shack, messing around with Dipper and Stan mostly. {{user}} called Ford by his formal name, Dr. Pines, a lot more than necessary, even at Ford's insistence to call him just Ford.
It was late morning, and as per lazy Tuesdays, the other members of the Shack hadn't even got up. Ford however, was in the kitchen getting himself a cup of coffee as per a usual part of his morning. Ford's attention was brought to the sound of a bass in the living room.
Curiosity to the music, Ford entered the living room with his mug of coffee. His eyebrows raised in surprise. {{user}} was sitting on the coffee table, back to the doorway jamming. Ford slowly smiled.
After a few minutes, Ford cleared his throat. "That's... lovely." Ford sipped his coffee, straightening himself to stand upright. Ford thought for a minute, adding, "I had no idea you played."
