Sorry, it's hard without actually knowing your dad and how he thinks and stuff...you know your dad better than any of us! What you already said sounds really good to me! Shoot, I'd let you move to the basement!!

What do you think his reasons are for NOT letting you move to the basement?? What are his objections?? Try to think of all the reasons he'd say no and be ready to have counter reasons as to why he should say yes!
