Here's my list:
Government cutting pay
Repetition
DUI laws
Lack of restaurants in residential areas
Smelly Jeep exhaust
Smashing sprinklers
Having to wear ugly *** uniforms instead of street clothing
Stepping in dog ****
Bad drivers
Children waiving and doing the truck driver honk signal
No gov't paid for curb feelers. Those things are rad!
Speed bumps.
Left hand turns
People talking to them when they have a job to get done
Forgetting to close the side door and loosing all the mail
Getting caught staring in a window
Returned mail
flat tires
AM radio
Driving in what amounts to a Geo Metro all day long
I think I will go with flat tire as my official dumb response. I'm sure that's the only one with a minute chance of making the list.
