When somebody leaves a message on your voice mail, telling you that they are at the sporting goods store, and that they are going to need some help moving a new safe IN A COUPLE OF DAYS....
You do NOT head straight over to their house without calling them, while they are still on their way home from across town.
And UNDER NO CIRCUMSTANCES should you announce to his wife, that you are there to help move the new safe.
This is a violation of the Man Card. With extra demerits for doing it to family.

That is all.
