As part of our untiring efforts to make life easier for overworked project directors, here are some of the more original responses to evaluation propositions, collected by a colleague in another organ of the United Nations System. When a single reason is not enough, one can always give two or three, for example, "our  project is different and the costs are too high". However, one must be careful that the two reasons given do not contradict each other, for example, "we are constantly evaluating" and "it's impossible".
