We easily demand patience, punctuality and responsibility from others. The true weight of that demand is seen when the same standard becomes unpleasant for us: when we are late, make a mistake, or get an answer we don't like.
People notice the difference between what we say and what we allow ourselves to do. The explanation of our own omission may be correct, but it does not erase the obligation we have assumed. How we behave when we have more power in a relationship is especially important.
An example is built with ordinary actions: a fulfilled agreement, admitting a mistake, respecting other people's time. A request that does not apply to us loses its credibility over time. Others are left with the message that the rule is just a way to get more out of them.
