I have an easy trick for predicting what people will do in the future.  Look at what they did in the past.  They will do the same thing.

We have a tendency to expect people to change, especially when they are doing things that we don’t like, or that are hurtful to us.  However, people almost never change.  People are who they are, and they always will be.  They will continue to do whatever they did in the past.

The next time you are surprised when someone close to you does or says something bad to you, stop and think about it.  Should you really be surprised?  I bet they have done the same thing in the past.  And I will guarantee they will do the same thing again in the future.

So prepare yourself the next time.  Remember what they did, and expect them to do it again.  It makes it easier to deal with someone else’s bad behavior if you’re not surprised by it.
