"Hi, what's your name?" Sherlock said to the boy sitting alone at a lunch table.
The boy looked up from his sandwich (PB&J) and gathered Sherlock in a glance, saying nothing, but chewing thoughtfully.
Sherlock tried again, "Mind if I sit here?"
The boy didn't answer, so Sherlock sat anyway.
The boy sputtered a bit and took a swig of his milk. His mouth had been stuck together with peanut butter, rendering him unable to answer.
"No, wait I'm saving this seat for my friends." The boy said.
"So you want me to leave?" Sherlock asked.
"Yeah."
Sherlock picked up his lunch in disgust and went to find another free seat.
