Stop defending people who will not help YOU defend THEM

You are going to have people in your life who will constantly rely upon you to defend their actions.   

In most cases, you will not mind.  However, some of these people will make it hard for you to defend them.  

Mostly because they KEEP doing things to make it harder to defend them.   They will tell you that they will not do the same thing again.  You will defend them and they will go and do the EXACT same thing again.   

It is important to know that if the person is not trying to help you defend them, then they are just using your reputation to give them cover.   

At some point, you have to accept the reality that if they do not help YOU defend them, you can not DEFEND THEM.
