To the boy at Walgreens

Checker Boy: "He has something in his mouth."
(looking with disgust at Greyson's small contraband that he picked up from no telling where)
Me: "I know." (Sweetly smiling but secretly wanting to throttle him)
Boy: "Do you want me to throw it away for you?"
Me: "No thanks. It's buying me a little time - I'll take it from him in a minute. I guess you can tell he's a second child, huh?"
(Hardy har har. Please just laugh along with me so I can get out of here)
Boy: Silence and stare of incredulity.

I'm thinking that checker boy was a second child, too.
