Parting
Milly said her new assignment was pretty safe, but Jean knew her baby sister was lying. She approached her sibling alone.
"Milly," Jean said, staring the other in the eye. "You're goin' someplace dangerous, aren'tcha?"
"..."
"I'm not gonna ask where; you'll prolly lie about that, too."
"Our assignment is to monitor Vash the Stampede."
"... I see."
"..."
"Welp, guess you better write home a lot! Here." Jean held out a box. Inside, Milly found paper, pencils, and stamps. She started to cry.
"You leave nuthin' out, got it?" They hugged. "I love you, baby sis. We all do. Come home safe."
And so begins the Milly Monthly! I have no idea why Milly's sister talks that way. It just sort of happened.
