Thank you cards are pretty high on my importance list. If kindness is extended without the opportunity of face-to face thank yous, the least one can do is take a few moments to show appreciation for such thoughtfulness via a a phone call, a visit, a hand written note...So I've begun to make sure my boys are aware of this concept and am helping them "learn" gratitude. I spend a lot of time teaching them to think of others. Here's a simple way I had N create a thank you card. I typed the majority and had him write basic parts to make it his own. The card is his traced hand holding a heart. So go ahead and remember to have your children show appreciativeness and generosity!
