Wash said he didn't want to go shopping for a while because he couldn't concentrate on that and his surroundings. I guess he maybe came close to taking a swing at Charlie's boss when he got surprised and he's worried he'd hit some normal shopper if they startled him. I know I'll feel better about him not doing it yet, it'll be holiday time soon and people are nuts.
I'm kind of feeling out someone about helping out with that and a few other things.
