<human>: Can you provide a brief rundown of the text in within 3 sentences?

A very dear friend of mine and I are leaving for college in about two weeks. The problem, though is that we're both moving to the respective towns we're attending college in and they happen to be 7 hours away.

We both know that the last day we will see each other is August 14th, and I wanted to get a gift for my friend that will show her how much she's meant to me and is something that she can keep for a long time.

I was thinking about making a picture frame and then putting a collage in it that details our friendship (pictures of us, mementos, inside jokes, and generally things dealing with our friendship) but I'm worried that it will seem trivial after a short period of time. I wanted something that would allow her to remember us years from now.

I just want to be able to walk away from our last day together not overly-emotional and knowing that my gift has been helpful to her in dealing with the fact that we may never see each other again. 

If you've ever dealt with a similar situation, I'd also love to hear about it and how you dealt with it!
<bot>: Have you ever had to give a long-term going-away gift and, if so, what did you do/ what are some suggestions for such gifts?
