A missive noting that while one's absence will be noticed, it does in fact provide a chance to remodel the prior living space.  Also a list of nonsensical items to be sent, none of which will be overly useful.  Such items may or may not include stickers, bouncy balls, a post it, and perhaps a confection.  We are not limited to that list, or commiting to it.  It depends on what we feel like that day.

(Contents and letters will vary!)
