I want to make my dad mad
Did your dad do something to make you mad?
I saw his inappropriate pics on Facebook and it made me angry.
Parents can do things without thinking sometime. Just talk to him about what he's posting on Facebook, and make sure he knows that it's upsetting to you. Making him mad will just lead to problems in your relationship with him.
He's an old man, he's going to die soon anyway. I'm tired of everything he does. I think I'm only going to make my life better by making him really mad, so he stops bothering me.
Trust me, your life won't be better without your father in it. Just try explaining how you feel about what he's posting, and then if he still wants to post offensive pictures block him and stop looking at his page. You can't control what he posts, but you can choose not to look at it.
