No offence but it's your dad who needs to grow up. Yelling at the tv while eating dinner. In my house or at least when I was growing up there was no TV allowed on while we were eating. That should be a time to interact with each other. And it wasn't right of your mom to blame you either.

So don't feel bad or take it to heart. Sometimes it's the adults who need to grow up. No fault of your own.

Take care
