We got a letter in the mail from Burlington asking you to let them know if you are going back. I assume this is part of the standard letter everyone got, but wanted to let you know that it had arrived.
I was tempted to write back something vague about how I liked it warmer and "he's too nice to me to give up" but that's stirring up trouble in an e-mail account that I would like to keep. So I just let "Mom" know that she needed to add a middle initial to the e-mail address and wished her well.
