Would you like to know a stupid expression with no use in the English language? Of course!
“At this time.”
It’s meaningless. “The voicemail box is full and is not accepting messages at this time.” Why the hell say, “At this time” when you can say, “…not accepting messages”?
“I’m not interested in having sex with you. At this time.” You can always change your mind later and say “I am interested in having sex with you.” The “at this time” would be damn well understood. At this time, no one has time to read the phrase, “At this time.” Leave it out 99.44/100% of the time.
While I’m on a grumpy tear, what about “do” Who added that to the helpdesk script? “I do apologize at this time.” What about, “I apologize.” Get the job done, move on. That’s what excellent writing is: say it and leave.
As Mary Poppins would tell you, “Don’t dawdle.”
