need I remind you (that)
A slightly condescending introduction to a reminder of some fact or situation. Need I remind you that you are still bound by the obligations of your parole? This sort of behavior will lead you straight back to prison! I understand your sentiments, but need I remind you the profitability of our company is the highest priority?
need I remind you that...
and need I remind you of...a phrase that introduces a reminder. (A little haughty or parental.) Bill: Need I remind you that today is Fri-day? Bob (sarcastically): Gee, how else would I have known? John: Need I remind you of our policy against smoking in the office? Jane: Sorry, I forgot.
