Some people might avoid it, but I could disagree...
Interesting expression John. It baffled me at first, but
this forum gave a good definition of it. According to what they say, some people think that "talk to my hand"
1. began in the 1990's among Afro-Americans.
2. alludes to the gesture of putting the hand, or both hands, in front of the speaker's face to express refusal to listen.
3. is considered too "low" for some "high-minded" people.
I think the expression is quite creative and vivid enough to be used by anyone in any situation of refusal. I'm no playwrite, but let me try a little adapting from the Grimm brothers.
"The wolf came back from the miller's and knocked on the door for the second time saying, 'Children, I'm back. Open the door!'
Brother lamb replied, 'How do I know you're my mother? Show me your two hands first,' at which the wolf slid its dough-covered paws through the cat hole in the hope of tricking the sheep into thinking he was their mother.
Brother sheep, seeing the two paws which were made up to look like Mother's hands, struck down with a sledge hammer so that the wolf had a great pain running up and down his spine. The wolf, cried in agony, 'How could you ! I'm your mother ? You ungrateful child. Damn you, and open this door before I huff and puff and blow the house down.'
Brother sheep laughed at his arse saying, 'Well, you can talk to my hand all day, but I already know you ate the three pigs.'"
