In an honors English class (years ago), our assignment was to write instructions on how to tie a shoe lace. It was quite funny to see how badly this can turn out. Also, it was quite instructive to see how difficult it is to put into words that another can follow, tasks that have become second nature.

How would you word it?

Or are there other things that you thought would be very simple, but turned out to be much more difficult than you thought?
