You know what it is like you bump into someone and you have seen them before but the name - it's gone!
Standing there in desperation sieving the corners of your mind not really paying attention and trying to be nice and kind.
If you say the wrong name you are in a sticky situation Got to say something and it is back to the old desperation.
So you start clutching at straws feeding in bits of "I want a clue" Searching through the grey areas in the mind wondering what on earth to do.
But the mind plays tricks on us dont we know and it has us wiping the floor. When thank goodness a good thing to say is Have I seen you somewhere before?
