People who don’t understand your boundaries don’t deserve your attention. You see, if you let someone take over your schedule one time and not say anything about it, then that person will get used to it and expect you to let them take over your schedule over and over again. Only, they won’t think that they are taking over your schedule. To them they get to be themselves around you and it’s all normal and good. So as soon as you feel someone overstepping your boundaries you feel a tendency to cut them out. But the problem is, if you do this every time someone consistently oversteps your boundaries, there may be no one left. What do you do then? You have two options. Either talk to the person about it or compromise. If you don’t do either, a huge fight is on the horizon.
