[you] and I used to get along fantastically when we were in school together. As fantastic as it may seem, we lost track of each other after that. One day, [you] and I bumped into each other downtown and we had a fantastic reunion.
I asked, "How have you been [you]?" And [you] proceeded to tell me about the most marvelous person [you] had married. I said "fantastic."
Then [you] told me how they had the brightest children. I said "fantastic."
Then [you] told me how they lived in the finest house with all the newest and finest furnishings, appliances, decorations, and gadgetry available on the market. I said, "fanastic."
Then [you] told me how they went on vacations every year to the most exciting places. Of course, I said, "fantastic."
Eventually the topic of conversation turned to me. [you] asked me what I had been doing all these years. I said, "I went to charm school."
[you] asked, "What did you learn in charm school?"
"How to say fantastic when what I really mean is bullshit."
