I hate everybody . . . and other myths

I don't know how many of you in law enforcement get this from your significant other/family members regularly, but I get it every once in a while. Every once in a while they drive it into the ground.
"You hate everybody." "You're grouchy all the time." "You won't trust anybody." "You're like talking to a rock when you come home from work." "Somebody from WORK is on the phone for you." "Why do you have to take a call from a supervisor if you're not at work?"
You get the point.
Here's the thing, I don't trust many people. Unfortunately, sometimes that includes people I work with. I am not about to tell people at the grocery store, your barber or the guy installing my cable that I am a cop. Sorry. Not happening. Don't get crappy when you get "the look" shot at you for telling random people "Oh do you know what she does for a living? You'll never guess . . "
I work 12 hour midnight shifts. I'm not grouchy, I'm tired. Okay, who are we kidding here? I am grouchy. That's because I want to go to sleep in the morning. I also want to sleep without getting awoken to "Hey, do you know where the can opener is?"
If I told you what actually happened at work, you would panic. I'm just saying. Some of the guys I work with are spazzed out after things we do.
Public safety unfortunately is not a 9-5 job where you leave everything at work. There are times when work calls and you have to answer. Somebody got seriously injured at work. There is a shift shortage and you are getting called in early. Your vacation is approved/denied based on coverage. Surprise! You have/do not have court today.
So here's the thing; I'm sorry. It's nothing personal, I'll try harder. How are you supposed to explain to your friends and family how to handle you when you spend most of your time trying to figure out how to handle everything else?
