with all due respect恕我直言。due在此處指「應當的」，這個習語字面上的意思為「秉持著尊敬"，但在實際使用時，是因為接下來講的話或許會冒犯他人，才會用這句習語。需注意的1，有些人會把這句i看作是你在汙辱t的智商，使用時請多加小心。
看看老外聊天時怎麼用with all due respect：

Larry: Yes. And we need to come up with a proposal in that time as well.
Rita: With all due respect, that's not nearly enough time.
Larry: I understand how you feel, but we have to accept the terms.
Rita: We can at least ask for a bit more time.
麗塔：我們必須在一周內完成實地調查嗎？
拉裡：沒錯，而且還必須制定一個計劃。
麗塔：恕我直言，給的時間根本就不夠。
拉裡：我理解你的心情，但我們必須接受這樣的條件。
麗塔：那我們至少可以要求多一點時間吧。
