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 cheque inside. I never hear from them neither receive a thank you message !”
Ruby replies. “I too send them a very generous cheque. I hear from them within a week after they receive it. In fact, they each pay me a personal visit.”
“Wow !, How come ?” remarked Dolly.
“Very simple solution, *I don’t sign the cheque.”*
