荷莉：这个嘛，如果我改变不了你的心意，我就……我就在你离开之前，为你办一场盛大的感恩节大餐！

Holly: Well, if I can't change your mind, I'll... I'll make you a huge Thanksgiving feast before you go!

你可以费尽口舌，但改变不了我的主意。

You can argue till you're blue in the face, but you won't change my mind.

《牛津词典》

原谅我这么说，但是那些令你苦恼的决定真的改变不了什么，比如你把房间刷成什么颜色，你是否应该让孩子做某事，你在哪里度假等等。

I'm sorry but those decisions you agonize over just don't make any difference. The color you paint your house, whether you should let your child do x, where you go on vacation, etc.
