Ok, this is a little odd, but since it happens to me fairly regularly, I thought I'd ask peoples opinions.
I have a three year old, said three year old is in a car seat still (and still needs to be buckled in by an adult.) On many occasions I've had the driver of the car next to me (car seat side) get in and start backing up WHILE I was buckling my daughter into her car seat. This means door open and INCHES from their car while I'm standing behind the open door. In other words, if they back up and their car catches my door I will be injured, perhaps seriously injured.
Normally when the driver starts backing up I quickly turn around and give their car a thump. Enough to get their attention but not to damage the car. Sometimes I get a sheepish "sorry" look and they wait for me to finish (note, I'm not being slow about it, I get her in there and buckled as fast as possible), sometimes it leads to a verbal argument between me and the driver. I've never had someone get out or threaten me but I realize that this could be a possibility.
I realize that a gun is a LAST resort. (I don't currently carry but I'm working on that.) And that this situation shouldn't EVER lead to me having to draw, but....their are crazy people in this world. Could my thumping their car be considered an escalation? My gut tells me yes, but I don't know how to get their attention and keep me safe otherwise in this instance.
I'm willing to be the lesser "man" always. (I'm a woman.) I have no problem with them starting to rant at me and saying "Sorry, I didn't know if you were aware I was there and I didn't want to get caught between my door and the car if your car were to hit it. I was just trying to get your attention, not damage your car. I'll be done in just a second, thanks for understanding and being patient."
I do try to park with the car seat side twords a non-car (curb, cart return, etc) or to park a few stalls away from others at the end of the lot, but its not always possible.
Anyone have thoughts on this or how to handle it? Like I said, it should NEVER lead to a weapon being drawn, but crazy people being what they are, I could see me thumping a car leading to a 6'4" 300lbs A-hole jumping out of his car with a tire iron. Just looking for alternate ideas from those with a good level of SA.
