Shelly's school let out earlier than Stan's, so she had a house key. Their parents took Stan's away after he had lost three or four and they kept having to change the locks.
She rushed home, unlocked and locked again. She felt great, she got first access to the good snacks and the tv.
She heard a knock a moment later. "Come on, this isn't funny Shelly!" Stan knocked on the front door and window.
She took off her headphones and laughed quietly at her stupid brothers.
"Fine, I'll just go to Kyle's."
Perfect. She had the house to herself.
