My dad really frustrates me?

Your Dad is obviously devastated that his beloved business that he's probably put everything he's got into it and now it's gone, he'll be feeling maybe embarred that it's happened to him and his family and now he's grasping at straws. Why dont you speak to him about it, maybe throw some ideas around together? And yeah as Pearl says! As the other man of the house you shouldn't be moaning about it you should be stepping up and contributing to the family, help them get the family back on their feet!
