Look What You Did
Stuff like this reminds me of that scene at the end of It's A Wonderful Life (one of my favorite movies) where everyone in Bedford Falls helps out George Bailey.
"Merry Christmas, you wonderful old building and loan!"
You gave $50. You gave $500. You gave $5. You gave $25. And we've raised over $2,000 for our future. We hit the goal. So now we aim higher. Give what you can.
