I’ve been told that one of the signs of an insane individual is someone who continues to perform the same action while expecting a different result. I do this on just about every work day.
We have a soda machine (that’s a “Coke Machine” for my fellow Texans). It takes dollar bills, sometimes. I feed it my dollar. It spits it back out. I feed it my dollar again, in the exact same fashion as before, it spits it back out. I feed it again. It spits it back out, again. Eventually, usually, it gives in to my persistence and takes my dollar.
This morning’s soda took 11 attempts. I think that’s a record. I should keep track of these things.
