I don't want to hang out with my dad
I'm sorry to hear that, did the two of you have a disagreement?
I am too busy with my studies to spend more time with him.
I understand how hard you're working. Your dad loves you and wants to spend time with you. Maybe you can make time to meet him for lunch once a week? I'm sure you'll both really enjoy it.
You know nothing!
I think you might regret not spending more time with your dad. One lunch a week or every couple of weeks wouldn't take too much time and the both of you would enjoy it.
