"It's only decent to warn you that you will be bored to extinction. It was a thoroughly dull party from the beginning, but if you will come I shall be uncommonly grateful. And you and I can have a little chat by ourselves."
It was only neighbourly to accept.
在上面,出现的2处only用法不懂。
It's only decent to warn you 和 It was only neighbourly to accept. 中,这2处的only用法含义一样吗? 应该如何理解呢?
