It's one of those things that comes out of the mouths of irate toddlers who don't want to do as they're told. And sometimes - let's be honest here - it can be what we think, accompanied by that mental foot stomp.
Yes, it may be childish.
Sometimes it's the right reaction.
A lot of the time we acquiesce to requests to keep the peace. And that is what they are - requests. But if we're not careful, we can let ourselves be manipulated, especially when those requests insidiously turn into orders and the person involved expects you to jump to their command. It is too easy to abdicate responsibility where we should stand up to the person involved. There comes a point where we have to say, 'Enough!'
Sometimes we allow people to have power and authority in our lives that is not theirs to have.
Make sure you know whose orders you're willing to follow.
