“I. Need. Amacackas,” says Sebastian patiently.

“What, sweetie?” asks his mother Fern.

“Amacackas!”

She shakes her head. “I just don’t know–”

“I! Need! AaaaaaNGH.”

“Sebastian!” Fern rushes over to him. “What did you do?”

“Borrowed some time from a potential future self, probably,” says Sebastian, and glances down at his diaper. “What am I, here, about two?”

Fern gapes.

“It’s quantum,” says Sebastian, waving his hand. “Don’t worry about it. Okay, is there an emergency?”

“I,” says Fern, “uh. You wanted something? But I didn’t know what.”

Sebastian furrows his little brow.

“I think it’s animal crackers,” he says at length.
