One thing you should do when your parents make a mistake is learn to talk about it. Don’t feel like you have to avoid talking about the mistake, especially with your parent. Don’t bring it up in the situation of every fight you have that follows the mistake, but instead, sit down like an adult in a mature way, and ask them if you can talk to them about it. You may not really want to do this, but doing so will help both of you sort out emotions you’re dealing with. After all, your relationship depends on being able to talk about things, and isn’t just about what mistakes either of you make. If you can't talk to them, or they refuse to talk to you, be sure to talk to someone you can trust and confide in.
