#1) Bad drivers. But to be more specific, what I hate most is when people don't use the left lane as a passing lane. Instead they line up with the car to the right so its like a 60mph drag race. Or 60mph cruise. No way to pass or weave around these people

#2) People who have the audacity to run loud machinery (mowers) at 8am on a weekend morning.

#3) People on the cell (and bluetooth included) at restaruants. TAKE IT OUTSIDE!!!
