Something which is pointless, has no purpose or meaning and is a waste of time. The phrase I would say that wouldn't I? is a tag question meaning, 'of course I would say that'.
某事pointless指没有目的或意义、浪费时间的事情。短语“I would say that wouldn't I?”是一个附加疑问句,意思是“我当然会这么说”。
Just as a quick review, those four strategies are using that falling intonation, slowing down your speech and pausing. You can use tag questions or ask questions to get someone else into the conversation.
