Also, avoid raising your voice. The person who feels that they have won is the person who yelled the loudest. Again, work at listening to what they are saying. You may need to take some time to reflect on what they are saying. You need to ask yourself if you are willing to change your own opinion about the problem too.
Flexibility is important.
Try not to approach the problem with a rigid attitude bent on getting your way no matter what happens. You should also allow time to negotiate the decision. There needs to be some reasonable give and take on both sides. After this is done then both should decide on a plan of action. Working through problems will take some time, but this is necessary in order for growth to take place between you and your stepparent.
