So up in my room I have a blue gift bag. Inside of it are all the cards/little books/trinkets that I got when I graduated. Its quite an ego boost reading about all these people saying how proud of you they are....and how you're off on an adventure. A couple years later I still don't know what I want to do, oh well.
But the moral of the story is, look through old cards. I found a $10 Swiss Chalet gift certificate in one.
