The purpose of this paper is to present and discuss a puzzle involving accommodation. The puzzle is based on three assumptions. The first assumption is that accommodation takes place after an utterance. The second assumption is that accommodation can make a difference to the truth-value of an utterance even if the utterance is not about the future. The third assumption is that something that takes place after an utterance cannot make a difference to the truth-value of the utterance unless the utterance is about the future. Since these assumptions are jointly inconsistent, one of them must be false. The question is which one we ought to reject. The majority of the discussion is devoted to discussing each of the options, and the tentative conclusion is that the most plausible strategy is to reject the third thesis. That amounts to saying that something that takes place after an utterance can make a difference to the truth-value of the utterance even if the utterance is not about the future.

本文的目的是提出和讨论一个涉及住宿的难题。这个谜题基于三个假设。第一个假设是适应发生在话语之后。第二个假设是，即使话语与未来无关，适应也会对话语的真值产生影响。第三个假设是，在话语之后发生的事情不会对话语的真值产生影响，除非话语是关于未来的。由于这些假设共同不一致，其中之一必定是错误的。问题是我们应该拒绝哪一个。大部分讨论都专门讨论每个选项，初步结论是最合理的策略是拒绝第三个论点。
