Of at for... I'm afraid of spiders. Why are you afraid of dogs? Is she angry with you?
I’m not angry with my father. My dad has been angry with me since November. I’m angry about the situation. Is she angry about the exam?
I was angry about your behaviour. I’m very different from my sister. She is very different from her mother. I’m fed up with my job, I want to do something different. Is she fed up with her family? I was fed up with my life, but things has changed. I’m very good at maths. He isn’t very good at music. 
I’m very interested in music. I’m not interested in politics. Are you interested in history? I am married to a beautiful woman. She is married to a dentist. He has been married to a teacher for twenty years. I’m sorry about the situation. I can’t help you, I’m sorry about that. I’m sorry for not listening to you while you were talking. She was sorry for treating me so badly. He is sorry for laughing while you were speaking. He is so sad, I feel so sorry for him. They are in a terrible situation, I feel sorry for them. Look at John. Don’t you feel sorry for him?
