I've been driving for a while now and I've overcome some major obstacles. I learned to drive a stick shift (ask my sister how well I did when her head stops bobbing from all the jerks and stalls), adapted to driving in a bigger city and made it through last winter without keeping my kids home from school all winter simply because I LOATHE driving in the snow.
Now, I've only been driving for eight years but I've gotten through mostly incident free. I don't count the time I took a friends side-mirror off with a pole (it wasn't my car- so it doesn't count). I also don't count the time I forgot there was a parking barrier in front of me (there was a road on the other side and I couldn't see the barrier from the driver's seat... plus I was tired from working out) and ended up straddling it like a turtle on it's back, when I gunned the car.
As I was saying: I'm a mostly-incident free driver so I think I can safely assume I know some basic driving etiquette. Now, I understand that most road rules go out the door in the school parking lot but there should be some sense of "hello I have basic parking knowledge." It's a free for all when when that final bell rings. So I'm generally forgiving (or I at least mutter under my breath) when a car drives the wrong way through the parking lot (it's marked by arrows, hello!), parks in a handicapped spot or darts across the front of my car like a jackrabbit and expects me to stop on a dime. But, I don't forgive parking spot hogs.
There are a limited number of parking spots at the school. It's like winning a lottery to snag a spot. I have to get to the school 10 minutes early on a sunny day to get a spot and in the winter- I show up 30 minutes early (note that I hate driving in the snow so I take my time). How hard is it to park your car in ONE spot. When you get out of the car and notice you are sitting squarely in two spots, it's time to hop back in and repark.
I was sorely tempted to write a thank-you note to the guy hogging two spaces after I rolled around the parking lot three times waiting for spot to magically appear but I didn't have a piece of paper, plus I wasn't feeling very kind and you know what Thumper always says... "If you can't say something nice..."
