I hate when it rains from Cincinnati to Atlanta and doesn't stop. (For those of you playing along at home, that would be 6 1/2 hours of driving in continuous rain)
I hate that I can never figure out the perfect interval speed for the wind shield wipers and that I can never, ever seem to figure out how to defog a windshield properly.
I hate when I stop to get gas in BFE, Tennessee and to my left is a tanker truck blocking the left exit and to my right is an old man who conveniently decides to back into a parking spot but only backs in 1/3rd of the way and is blocking the right exit. Fabulous.
I hate, while sitting at a sushi bar, the waiter, who keeps saying, "I'm sorry. I have short arms" keeps reaching past me, while putting his armpit in my face, to get sushi for his tables.
... but I do like seeing my friends and family, so its all worth it. ;)
