Is it just me?

Is it just me or does your mind go completely blank sometimes when asked a very simple question? Maybe there was not a lot in there to start with! Graham just asked me for a verb – easy question there are plenty, could I think of one at the time? Not a chance, completely blank.. lights were on but no-one home.  Sometimes we are trying to think of twenty things at the same time and the brain just does not compute! I am sticking to that excuse anyway!
