I never understand the ones that wait unitl you're virtually on top of 'em and THEN they move away. Slowly. Now, you've had plenty of time to go whilst I was approaching. But you haven't. So what's changed?
Further, there's a 1/2 of clear road behind me.
But, having wandered out (as if it's that important to do so, having waited for several hours to do so) and caused me to have to adjust my speed you now proceed to spend several weeks getting up to speed.
So, if there's such urgency to your cause that you need to drive directly across me, why, then, having done so has the same urgency suddenly disappeared from your mind.
If you're in a rush, then go, go soon and GET ON WITH IT.
And please don't gesticulate to me when I pass you at the next available opportunity.
