 Re: draw a blank
Not that the phrases "mean the same thing" but that the co-text means that the full sentences end up meaning the same thing. As I said, change the verb in the first part and you change the meaning of the full sentence. But the meaning of the individual phrases remains the same : 1. I wasn't successful 2. I couldn't remember.
Another example :
The police had been investigating the murder for 6 months, but so far had drawn a blank.
Again, nothing to do with memory. |
