IM from Chris mocking emails from Nick with 100% accuracy:
hi elaine,
in about three hours i will send you an email to tell you that i will be sending you an email tomorrow that says i will be sending you an email on monday with some changes that may or may not need to be done on monday, but i won’t be able to tell you whether they need to be done then because i will not have access to email until next wednesday, when i will send you an email to tell you when my next email will be coming to tell you whether the changes need to be made.
