Where did it all come from??

I'm packing today. And every other day this month. =) But today I realized how much "stuff" we have actually accumulated. Honestly, some of it I hadn't seen since we moved into this house. Why do I save everything? Cards we got from our wedding...college photos still in frames of people I haven't seen in years. Macroeconomy books from classes that I took 10 years ago. What's the point? It must have been important to me at one point in my life. But now not so much. Good will be glad to see me pulling around the corner next week with a whole car load full of "memories" to pass onto them. You think they would take the 100+ stuffed animals my kids have?!?!? Lol.....
