My wife is always telling me I am terrible at estimating the time it will take me to do something. I was having a drink or three at the local pub and she called to ask how long it will take me to get home. I told her it took me five minutes to walk here, so it shouldn't take me any longer than five minutes to get home. Well, it took me 30 minutes. As soon as I walked in, she said, "See! You are terrible at estimating time. You said five minutes and that little stroll home took you 30 minutes. I replied, "You know, I think you're right. The difference between those two times is staggering"
