Bummer, Sweetie. I think you ought to be able to study Latin if you want to. Do you have any money of your own?
Possibly the teacher would be glad to get a replacement, especially if you offer to split the cost. And most universities offer used books (cheaper) at their bookstores.
This could be a win-win-win situation: your teacher would have a textbook again; you'd get to learn Latin; and your dad wouldn't fuss about another book in the house.
Good luck!
