Rhetorical ? To all who would give the miles back,

Do you apply this to the other areas of your life?

Rarely do I see righteous behavior in real life, kind of like the person who just left the church after sermon and is swearing at a fellow driver who isn't moving fast enough.

My reality would be:

find extra miles in my account, I use them.
find extra $ in my bank account, I use it.
Open package of clothes, found I was shipped an extra, I keep it.
Get home and find that cashier did not ring an item, yet I still have it, I keep it.
Friend who plays hooky from work on a Friday afternoon, I enjoy being with them and do not tell their company (even if I'm a shareholder)
Get double upgraded on a flight, I don't point it out and take a single upgrade.

See $ on ground that person in front of me dropped, I give it to the owner.
Store cashier gives me too much $, I give it back.

To me there is a difference between who I should be righteous with and who not.

Let he who is sin free cast the first stone.
