My brain has a terrible habit of taking one specified time and assigning it to a different part of the event. For instance, thinking that the time I need to arrive at the airport is actually the plane's departure time. Or the time I need to leave the house in the morning is actually the time of my first appointment at the office. You would think that I could find a way to correct this after several bad results. But so far I haven't found a way.

Does this happen to any of you? Is there a formal term for it, other than idiocy?
