Besides, he goes on, what reason have I for thinking that the earth must be the same shape as the sun and moon? I can't answer that one either.

A refusal that includes "don't" - as in, "I don't answer emails on a Saturday night" - is more powerful than one centered around "can't."

你的拒绝应该包含“不会”，比如“我不会在周六晚上回复邮件”，这比一个以“不能”为中心的拒绝语句更有效。
