He's a First-Class Guy

We went into Rite Aid today so we could stock up on Mr. Pitt's wine for the weekend. He stopped at the counter to talk with the cashier whom he knows, and I went to grab his two bottles of red wine (Yellowtail and Red Rock...in case you're interested). When I came back, Mr. Pitt and the cashier were laughing and chatting, seeming to have a nice time. When we walked out the door and walked across the parking lot, Mr Pitt said,

"Yeeeah...I like to B.S. sometimes."

B.S.?

"Yeah, yeah... I...I'll tell you when you're older."

I know what B.S. means...I just thought you actually liked talking to her!?

"Oh I do, I do...it's sincere."

So...it's NOT B.S.

"Well...it's sincere B.S."

Oh...uh. Ok.

"I'm a first-class B.S.-er!"
