I guess I'm over it. Can't always get my way even if it is the right way.

I think I've been doing good with my anger issues. I've been okay~not perfect but good.
My real trigger is people who drive 5 miles an hour. Philly has a street grid system and there are stop signs or a stop light on every block so you really can't go that fast anyway. I don't go fast. I go the speed limit~25mph. My skin starts to crawl when someone pulls in front of me and goes 5mph. Cause I know they're up there on their phone, playing with the radio, reading the paper or eating their breakfast/lunch/snack and I'm patient for about 2 blocks-thinking maybe they're just looking for a parking space but no, they stay in front of me and I pray "please, turn, please, turn, please turn..." 'cause I know if they don't~I'm going to start flipping out. Well, not really flipping out-just GRRRRRRRRRR and I hate getting GRRRRRRRRRRRRR 'cause it makes me feel like an idiot. Sometimes I'll start tailgating for awhile (we're only going 5mph!), hoping they get the point-but more times then not, they don't so I back off. Usually I turn and go down 2 blocks and keep going my way on another street-which, eventually some idiot pulls in front of me going 5 mph again.
I want to learn how to go 5mph without it irking me. How do they do it? Maybe I should bring a couple of magazines in the car with me and read while I'm driving like they do or play with a cell phone or bring my bag of make up and hair products and give myself a make over. ?????
