The Curse of Running Late: Traffic Problems

I'm not sure why, but every time I'm running late it seems that there are even more traffic obstacles than usual.  I think it is some kind of running late curse.

One of my biggest pet peeves is running late.  I feel that you should be at least 10 minutes early for any appointment and/or work.  I try to make it to everything 15 minutes early just in case something happens along the way.

But I'm human and there are days where I run late.  On these days it seems like the traffic does everything in its power to make me even more late.  I seem to get behind the slowest drivers ever, I always hit every red light and my car usually needs gas.

Why does this happen?  Is it just in my mind?  In my opinion, no.  I think that there are some evil monkeys controlling the traffic lights and all the slow drivers wait until people are running late and target them.  As far as gas, I'm sure I had gas yesterday.

Ok so many it is just a coincidence.  But why does it only happen when I'm running late?  For once I'd love to have a full tank, hit nothing but green lights, and be on the road alone.  Wishful thinking I guess.

What happens to you every time you're running late?
