我告诉自己，我不能坚持到永远。

I tell myself that I can't hold OUT forever.

我所想要的，并不理当属于我，而虽然它也不能以完全同样的方式拒我于外，但是任何人若坚持要做某种人或是想要某些东西，我们仍然会给他很微妙的惩罚。

What I wanted did not belong to me by right and whilst it could not be refused tome in quite same way, we still have subtle punishments for anyone who insists on what they are and what they want.

这就是棘手的地方：如果在你的生活中，有人始终不能坚持到最后，那么我将会将他们归类为有毒害的人。

Here is where it gets tricky: if you have someone in your life who is consistently not following through, I would classify them as a toxic person.

So, I insist, no talking. Please, no food or drink.

所以，我坚持不能交谈，不能有食物和饮料。
