Need Is The Mother Of All Invention

It was evening and Sylvia was in a different dimension altogether. 

To get in and get out of this dimension, she could only do so via a fixed gate.

When she was at a considerable distance from the gate, training Zen, a conversation between the two happened.

"Awooo. Woo. Woowoo!" Zen ran around Sylvia's feet in circles and howled. 

Sylvia, with an expressionless face, said, "Yes. Ren must be training too."

Zen then stopped in front of Sylvia, put his paws on her legs and looked up, right into her eyes. 

"Woof! Woof! Wooooo!" He began scratching her leg and pleading. 

"No. You cannot meet him." Sylvia said flatly in her monotonous voice. 

"Wooo…" Zen's eyes became watery and he continued to scratch his owner's legs. "Woo. Woof. Woof…"

Sylvia shook her head. "Saying you will be a good boy doesn't mean anything. Get back to training."

"Woo…" Zen was dejected and whimpered.
