A special circuit in the machine called a 'critical detector' senses the operator's emotional need in terms of how desperate he or she is to use the machine. The 'critical detector' then creates a malfuction proportional to the desperation of the operator. Threatening the machine with violence only aggravates the situation. Likewise attempts to use another machine may cause it to also malfuction. They belong to the same union. Keep cool and say nice things to the machine. Nothing else seems to work.
