When Personalities Clash

M and S have really, really been clashing lately. It is all verbal.

M said something to S, she replied, "TEC". He looked at her blankly.
"BDF, RCD," she said. He was looking at her like she had lost her mind.

She walked over to me and said, "What were those letters?"

I told her. She walked back over to M and with her most haughty look, hand on hip, hip thrust outward said,

"FYI, Maaaatttthhhheeeewwww."

He still didn't get it.

The rest of us were rolling on the floor laughing.
