I made this gift for a friend who was an exchange student this year...inside the box I wrote 20 "Open When" letters and I made a little memory book of old messages and old photos that I taped to the small pages. This is a perfect goodbye gift and although it takes a lot of time and effort, it's a homemade gift they can cherish forever! Tip for the "Open When" letters: it's never too early to start writing them! (it takes a lot of time)
