If The Shoe Fits

The saying is that you must walk a mile in your brother's shoes before you criticize him. This saying is totally inadequate.

First, you can't just walk a mile and be qualified to judge your brother. It has to be a particular mile: the very same one he walked. And in the same weather, too.

Second, you don't have access to his shoes.

Third, you don't have access to his feet. His shoes may fit you very well, but you don't know how much they may hurt his feet.

You have no idea whether you could walk twenty paces along that route, with those shoes, on those feet.
