Two old ladies Dolly and Ruby were talking about their grandchildren.
Dolly said, “Each year I send each of my grandchildren a card with a generous check inside. I never hear from them… never receive a thank you message.”
Ruby replies, “I too send my grandchildren a very generous check. I hear from them within a week after they receive it. They each pay me a personal visit.”
“Wow! How come ?” remarked Dolly.
“Very simple solution… I don’t sign the check!”
