When you're a mocker married to another mocker, practice never ends. Hell, you can practice during sex. Cross examinations are best done in bed, in point of fact, and my husband and I have the awards to prove it.

"You are aware that you were supposed to take out the trash."
"Yes, but I got busy and forgot..."
"Directing you back to my question, you were supposed to take out the trash."
"Yes."
"The trash is not empty."
"No."
"In fact, it appears to be overfilled with deritrus and flies are buzzing around it."
"I would dispute the characterization of the flies, but..."
"But you would agree that it IS, in fact, overfilled?"
"Yes, I would say that's an accurate assessment."
"Even though you were supposed to take it out."
"Yes."
"You DIDN'T take out the trash, did you?"
(sad look) "No."
"No further questions."
