i can't even remember the last time i put a new wiper blade on my car. Fern saw the potential danger in that and thoughtfully got me a new blade. but they'd run out of the blade for the passenger side so it's just for the driver's side. who knows wtf the difference is, but it doesn't really matter. he and Doug put on a new blade on the more important side of the car so when it rains tomorrow there's a slightly lesser chance of me dying from blindness. thanks guys!!!
