Hi everyone at good old Congress Elementary.  I wanted to express my gratitude for everything you have done for me this past semester.  I fear I have been spoiled and all other field work that I will be placed in the future will never amount to anything quite like your humble abode.  Thanks to people like y'all, however, I'll be able to breathe some life into my future classes.  Thank you all very much once again for the opportunity to serve at your institution.  This is by far not a "goodbye," because I plan to stay and help whenever I can.  It's more of a thank you for all that you've done.

Enjoy the faces... they're priceless
