re: What is the proper way to give cash gifts?

Put it in an appropriate card, be it graduation, wedding, birthday, etc.

I know as a kid and into my teens I really appreciated cash gifts so I could get what I wanted. It will be appreciated no matter how you give it to them.

When she holds the strap on her g-string out, you just slip it in.

Buy a card.

Reminder...parents buy your kids a pack of thank you cards and a book of stamps.

Make sure the graduate sends out those thank you notes. Old people expect and live for that shite.
