"Virg, I usually want to use the terms when specifically referring to tires. I have a slow leak in one of my tires, so when I go in to have it fixed I know now that it is the right front tire....or the front passenger side tire. I always had a problem knowing which was left and right because the guy at the shop would ask which tire it was....so I resorted to "passenger side" and "driver's side.""
In this particular case, when I dropped off the car, I'd just point to the leaky tire and say, "that one."
"I have a cheap digital camera. Nothing fancy. Have had it for years, and it's great for upcoming trips where I don't want to take my $800 camera. I left it in a box and the batteries exploded. There's a bit of that white-ish crusty stuff on the swing-arm of the battery compartment, but not too much, and it doesn't look like there's any within the battery compartment itself. Is there a way to salvage this so it still works? Or should I just write it off and look for another cheap one?"
Just clean it, dry it and then put in new batteries and turn it on. If it's messed up beyond recovery, it won't power up, and if it powers up then you cleaned it sufficiently.
"That reminds me of my stupid question: what is a car with four doors like? It usually seems to be five. I don't drive and I don't think that I've ever even talked to a car dealer before so covering for my collegue has been interesting."
A four door car is just a sedan (a front door and back door on each side of the car). A five door car would be a car with four passenger doors and a back lift gate, as opposed to a simple trunk.
