Why greeting cards?
My Mom - rest her soul - was a wonderful "Nanu" to my children. I honestly believe she loved her grandkids more than her kids, and I am okay with that! Every holiday, she would send the grandkids a card with a two dollar bill. I wouldn't let my boys spend those two dollar bills, I kept them in an envelope in my fire proof safe. Through financial hard times, divorce and relocating - I never dipped into their two dollar bills. Last Christmas, I gave the boys - now adult men - their two dollar bills - they each had over $300 worth. They were so excited that I had kept them from spending them on candy or some other fleeting desire.
