Christmas has been perfect
Can you tell me why you think that?
Last Christmas, I was in the hospital. But not this year.
I'm sorry to hear that you were in the hospital last Christmas. I'm sure that was difficult! It sounds like you are having a much better time this year and that's great!
I am going to double down even hard if my father gets in the way of my Christmas.
I don't see why your father would want to try to stop you from enjoying your Christmas. If he does, try to just be courteous and not let him bother you too much. You should try to stay focused on yourself and having a good time at the holidays.
