Excuse me!!!!

While Bobby was at preschool this morning, I took Brody and Natalie to the grocery store and got a huge scare and an eye-opening experience.
Brody is my run away child so I already had him secured in the grocery cart as I went to get Natalie out of the car on the passenger side. I opened the car door and started to pull the handle to release the car seat as I see this old woman open the driver’s side door to my car! Instantly I start thinking, “what is this lady doing?!?!” My purse was on the front seat and she starts feeling around on the floor and begins to climb into the driver’s seat. I start screaming, (well…I tried to scream)…”HEY! HEY! EXCUSE ME!!”  She of course doesn’t hear me, mostly due to the fact that I can’t raise my voice and she was probably hard of hearing since she older. She couldn’t hear me! I literally climbed up the side of my SUV, laid across Natalie’s car seat and starting hitting the drivers side seat!  I seriously  almost nailed an old lady in the head for getting into my car!  She then got really startled and began to explain to me that she thought it was her car, which she then pointed to her car that was next to mine. It was a much smaller SUV and not even the same color!  I proceed to get Natalie in the shopping cart and get my purse. The lady just walked away and continued to say she was sorry.
Now of course after this incident I started replaying the situation in my head. I was “screaming” the absolute loudest I could and this woman could not hear me only across the car.  Now she seemed very apologetic, but what if this was a real situation of danger?  I wouldn’t even be able to scream for help! This scares me beyond belief. Should I be carrying mace? Then, I think to myself that even if I had mace in this situation it would have been in my purse which was on the front seat, so it wouldn’t help.
Living in the suburbs you would think that I should be just fine, but you just never know.
After today’s incident, it really has me thinking. What would I do in a real dangerous situation? What if I am somewhere and something happens to one of my kids or myself and we need help? As I try to sit here and hope these situations never arise, I still need to figure out a plan.
This little old lady really had me thinking today…
What would you do if you couldn’t call for help in a situation of danger?
