A lot of the examples used here to frighten or alarm us are significant, and I hope that everyone is saying "I would never do anything that stupid". I fully agree with all the examples they are horrifying. However, there is one further example that catches out more people than all the rest. It has various names. Complacency. Familiarity. Laziness. And the favourite...Get-Home-itis.
I caught myself doing it once, and I sacked myself. I have a different mentality now.
