Irresponsible pet owners.
People who feel the need to give me "training advice" [also known as their very uninformed opinion about prong/pinch collars, electronic collars or choke collars] when they see my dog wearing a training collar.
People who tell me that feeding my dog raw food will kill her, or make her blood thirsty or aggressive.
People who tell me I need to spay my dog, and/or that it's healthier to spay/neuter a dog.
People who dress their dogs.
People who use those "Haltie" or "Gentle Leader" things on their dogs, and attempt to get me to share their delusion that they are "humane" training devices.
[Can you tell dogs are kinda a big part of my life?]
Poor table manners.
Hollywood movies with inaccurate Military uniforms, customs and courtesies, or weapon handling procedures.
People who do not know the different between there, their and they're. I can appreciate the occasional typo/slip-up, but people who honestly do not know the difference just drive me up a wall.
People who feel the need to tell me my Jeep Wrangler is a gas guzzler. Yeah dude, I know. I pay for the gas. I think I've noticed how much, and how often, fuel goes into it. I have a dog, a family and a penchant for off-roading. All things that are incompatible with a compact hybrid.
People who mistake a person's wearing of a Military uniform as an invitation for them to voice their personal opinions about the GWOT.
People who tell me smoking will kill me. Yeah, I know. I watched my dad die of cancer. I'm not a moron. I don't drink, I don't do drugs, I don't cheat on my partner, I don't beat her or my kid, I obey the law, I pay my taxes, I go to PTA meetings and I served my country in a *******ed war. I'm smoking a cigarette, outside, in accordance with the 25 feet from all doors and windows law that the state saw fit to implement. I'm not hurting you, so leave me the hell alone.
People who can't merge on the freeway.
