If a teacher discusses a unit with you well in advance, it is a certainty that she will be absent on the days scheduled, the substitute cannot administer the unit, and when the teacher returns she cannot do the unit because she has to make up for lost time. The one time of the month that you take 5 minutes to read MAD magazine is when your superintendent walks in. Prepare your year-end report in September before you have screwed everything up. If it's a good book, it's out of stock. If it's an excellent book, it's out of print.
Libraries are always empty when the principal or superintendent comes to visit.
The volunteer aide who files the worst is the one who volunteers the most. If you have a system that works you must be doing everything wrong. When you spend half your library budget on a teacher's request for a course the odds are that the teacher will quit or be transferred and the course will be dropped or changed. No matter how long you keep an article or piece of information you will never need it till you throw it away. If you have lost one issue of a magazine there will be 35 students who will require that issue.
