That weekend they gave us a ninety-six, and I took on Weissert duty for Friday. He was in the middle of a three-day drunk, and hanging with him was a carnival freak show filled with whiskey and lap dances. Didn't get home until four, after I dropped him off at Slaughter's barracks room, and I woke Cheryl coming in. She didn't say a word. I figured she'd be mad, and she looked it, but when I got in bed she rolled over to me and gave me a little hug, even though I was stinking of booze.

Slaughter passed Weissert to Addis, Addis passed him to Greeley, and so on. We had somebody with him the whole weekend until we were sure he was good.

When I wasn't with Weissert and the rest of the squad, I sat on the couch with Vicar, watching the baseball games Cheryl'd taped for me. Sometimes Cheryl and I talked about her seven months, about the wives left behind, about her family, her job, her boss. Sometimes she'd ask little questions. Sometimes I'd answer. And glad as I was to be in the States, and even though I hated the past seven months and the only thing that kept me going was the Marines I served with and the thought of coming home, I started feeling like I wanted to go back. Because fuck all this.

The next week at work was all half days and bullshit. Medical appointments to deal with injuries guys had been hiding or sucking up. Dental appointments. Admin. And every evening, me and Vicar watching TV on the couch, waiting for Cheryl to get back from her shift at Texas Roadhouse.

Vicar'd sleep with his head in my lap, waking up whenever I'd reach down to feed him bits of salami. The vet told Cheryl that's bad for him, but he deserved something good. Half the time when I pet him, I'd rub up against one of his tumors, and that had to hurt. It looked like it hurt him to do everything, wag his tail, eat his chow. Walk. Sit. And when he'd vomit, which was every other day, he'd hack like he was choking, revving up for a good twenty seconds before anything came out. It was the noise that bothered me. I didn't mind cleaning the carpet.

And then Cheryl'd come home and look at us and shake her head and smile and say, "Well, you're a sorry bunch."

I wanted Vicar around, but I couldn't bear to look at him. I guess that's why I let Cheryl drag me out of the house that weekend. We took my combat pay and did a lot of shopping. Which is how America fights back against the terrorists.

So here's an experience. Your wife takes you shopping in Wilmington. Last time you walked down a city street, your Marine on point went down the side of the road, checking ahead and scanning the roofs across from him. The Marine behind him checks the windows on the top levels of the buildings, the Marine behind him gets the windows a little lower, and so on down until your guys have the street level covered, and the Marine in back has the rear. In a city there's a million places they can kill you from. It freaks you out at first. But you go through like you were trained, and it works.

In Wilmington, you don't have a squad, you don't have a battle buddy, you don't even have a weapon. You startle ten times checking for it and it's not there. You're safe, so your alertness should be at white, but it's not.

Instead, you're stuck in an American Eagle Outfitters. Your wife gives you some clothes to try on and you walk into the tiny dressing room. You close the door, and you don't want to open it again.

Outside, there're people walking around by the windows like it's no big deal. People who have no idea where Fallujah is, where three members of your platoon died. People who've spent their whole lives at white.

They'll never get even close to orange. You can't, until the first time you're in a firefight, or the first time an IED goes off that you missed, and you realize that everybody's life, everybody's, depends on you not fucking up. And you depend on them. Some guys go straight to red. They stay like that for a while and then they crash, go down past white, down to whatever is lower than "I don't fucking care if I die." Most everybody else stays orange, all the time.
