After discussion (with myself) and considering comments of others, I’ve concluded that the letter of recommendation Karen wrote for me should be revised to something like this:
This letter is to recommend Sarah Harrison for the consideration of the Procrastinator’s Scholarship. Sarah has been a friend of our family since she was in grade school (and she’s still there). I have admired Sarah’s work ethic (wait till the last minute) along with the skills in leadership and decision making she has shown by always being the last person to arrive and the slowest to reach a decision. I highly recommend Sarah as an excellently late candidate for your scholarship. I firmly believe that she has and will continue slowly to merit this belated honor. Please take a long time, and then some, to reach a decision.
