Personally, I'd like to lean towards the second option. I'd like to say that my truck is a mess, inside and out, because I'm so busy doing stuff with it that I don't have time to clean it.
Of course, that could be a load of crap (ha, just one of the many things I use my truck for) because I suspect those clean, tidy organized people out there are actually capable of doing all that truck stuff and still find time to clean the truck. I admire that. I aspire to that standard, I really do, I just don't quite get there.
Having said that, I do like to keep a broom in the box. I sweep the box out every time I do a dump run. I hate when the bed's all covered in junk-crumbs. So I guess I'm not a total truck slob.
I gave it a good vacuum a couple weeks ago when the weather was nice. Sucking up the fine pieces of mud and gravel was nothing -- the real work, an almost impossible task, is getting all the Pug hairs. Pugs shed constantly, all year round, and I really shouldn't let him ride in the truck with me... but I have to! He's my DOG. And what do you do with a DOG when you have a TRUCK? Don't say put him in the back. He's right up there beside me in the Girlfriend seat where he belongs, dirty paws and extra hairs and all.
The last couple mornings when I drive the kids over to the bus stop, I've looked up in my half awake stupor and noticed little muddy paw prints right in my line of vision. Then I notice the rest of them on the hood. There's still a cat path running across the cab, except for the fan-shaped spot the wipers cleared.
Maybe I just don't care.
Maybe I like having a good supply of blankets and work gloves and shopping bags in the backseat.
Maybe I only have two arms and can't carry everything into the house.
Or maybe I have other stuff to think about.
Like how cute the Pug looks when he's plunked on the seat beside me with his happy tongue hanging out.
