Invisible Passenger?

 

While driving home the other day I noticed the passenger seat belt light blinking off and on.
Now, I knew I was alone in the car, but I had to glance over into the passenger seat anyway, just to be sure that someone hadn't snuck in while I wasn't looking.
Nope, no one there. But the darn light was still blinking. I look at the seat again, just a manila folder with 3 sheets of paper and my purse.
Hmm...my purse. Could it be? No, you have to weigh like a gazillion pounds to get the darn thing to blink, right?
Let's see, what is in my purse. It is rather smallish, only about 8 inches high by 8 inches wide. Made out of cotton by Vera Bradley. Inside, I have a couple of pens, an extra set of keys  What else,  lipstick, chap stick, a couple inhalers, tons of loose change, my glasses, my oxygen tank, cell phone and my wallet.
Holy $hit, do you have any idea the amount of change in my bag or how much that weighs?
Okay, I have now cleaned it out, let's see what happens next time I go out!
