Have you ever noticed how we cross the road early on our way to a place and cross it early in the other direction on our way back?
Why do we do this? Maybe a PhD student has spent years researching this — but it would probably take a year to find the relevant answer from her research. So I’ll give a guess. I think we like to get the hard part out of the way first and then enjoy the rest of the journey. I realize that is not true for all of us — and it is not true in every instance. But I think in this case it works.
Next time you walk somewhere, observe how you cross the road. Report your findings here, if you can remember to.
