No, it's an original. My father's friend is a calligrapher, and I had him make it for you.
没错,这可是真迹。我父亲的朋友是书法家,专门帮你写的。
I am sorry that you have a disagreement with your father. Personally, I think it is important to follow your interests and your abilities, and it sounds as though you have plenty of both of these already.
我感到遗憾,你和你父亲意见不一致。就我自己而言,我认为重要的是从你的兴趣和能力出发,听起来好像你已具备了这两点。
