walk a mile?

Would I ask you to walk a mile in my shoes?

No.

My shoes fit me as I have worn them for many many miles. The countless days, and nights of living my life have formed my feet and they in turn have shaped my shoes.

No matter how similar our lives might be or how close the size of our shoes, you would always find mine uncomfortable and learn nothing from that mile except that your own shoes fit better. Even more so; the more different we are in occupation, background, lifestyle, etc.

I never ask some one to walk a mile in my shoes. However if you care to walk beside me for a mile, I will walk beside you as well.

We both might learn something.
