This past Friday, I took DP and myself to the doctor, followed by a trip to the pharmacy. The pharmacy is inside a bigger store, which is in a very busy strip mall with lots of stores. The parking lot is well lit when it's truly dark, but this happened both at dusk (it wasn't quite dark enough for the lights to come on) and with some significant 'wintry mix' falling from the sky - rain, sleet, some snow.
I get DP loaded into the van, get her wheelchair in, and get in the van myself. I notice a car has pulled in behind us, and that the occupants haven't gotten out (I was noting this to be aware of pedestrians that might jump out as I'm reversing - it happens, a lot). I put my van in reverse, back out (slowly - see above wintry mix) and turn an immediate left (as we were in the first handicapped spot on the row). The row behind us was not handicapped at the front, just a standard row. As I turn, I hear a shouted "Thanks for your attention!! B*$*%" from behind me, and look in the rearview to see that the driver of the vehicle behind me and his young son are standing in the middle of the driveway that runs parallel to the shopping center (the drive I'd just turned on to from my parking space). Both are in dark clothes, hence hard to see, and dad's giving me the finger. Apparently they had gotten out as I was backing and I hadn't been able to see them (maybe both coming from the driver's side??), and had decided to cross the street as I turned, not noticing that I was turning (I had to go left or right, otherwise I'd have been driving into the side of the building, so the turn wasn't unexpected or cutting a corner).
Luckily, no one was hurt.
I know he was being PA, and rude. Was I in the wrong somehow? DP has said she didn't think so, but it's been bugging me.
