I've posted this before, so here goes.
At a meeting there was a woman talking about something or other, but kept revamping her point several times to make it sound like loads of points.
My first reaction was 'can she not use verbal punctuation' 'how has she not passed out due to lack of oxygen? she cannot possibly be talking this long and not take a breath'
I then progressed to 'will you shut the f**k up' 'Oh no, she's still going, will you shut the f**k up'
I continued the pattern until...
...the room went totally quiet and everyone was looking at me, apparently my IM had mission creep and I had verbalised my thoughts.
