Has this ever happened to you?

A: What was the name of America's first president?
B: I can't believe you don't remember that.Come on!
A: I konw. I konw. I've completely drawn a blank.

Drawn a blank?

She could not remember that George Washington was America's first president because she drew a blank.

It's another way of saying "I can't remember" something.

There's another meaning,too. If you're looking for something, but can't find it, then you "draw a blank."

In American English, you can use this phrase with friends or in business situations.

And that's English in a Minute.
