A questionable beer metaphor

Earlier this evening I was having a splendid chat with myself…

“John, my good fellow, I do say you’re having quite the evening.”
“Mighty good of you to notice old chap.”
“If you don’t mind my saying, you’re doing a superb job.”
“Why thank you. As it happens, I don’t mind at all John.”

This is where Cheryl rudely interrupted…

“John, did you give Beth her medicine?”
“No, I don’t believe I did.”
“Did you take out the garbage?”
“No, I don’t believe I did that either.”
“Does Adam need to be changed?”
“Dear Lord Woman, you certainly know how to shave the foam from a pint, don’t you?”

Give the gift of words.
