Aliens

So the strangest thing happened to me yesterday! After work I went to a friends house and parked in her driveway. When I started to roll up my window it exploded. Notice, it did not crack or break, it EXPLODED! I thought I had been shot at! There is glass every where! Has anyone ever heard of this happening? I am so glad I was parked or I would have swerved off the road! So today I am off to the shop to get a brand new, non exploding window!
