Hi Dr. Laura,
I just listened to the call from Rhonda on 6/28/17. She asked for some witty one liner when her grown son asks her for money. Here's what I came up with some 25 years ago when my brother used to do the same thing to me.
"I wouldn't want to deprive you of the pride of earning it yourself."
I was quite proud of myself for coming up with that, and he never asked me again! Double win. Keep on keeping on Mother Laura!
