If someone is good to you and does great things for you it would be nice if you created a certificate of appreciation for them. You don't have to go out and buy a card you can create one at home by hand or on your computer. You could just write a really nice note telling them how much you appreciate them and the things they do for you. Go into your Word program and create your card. The program
