This question niggles at me every time I have to deal with yet another ATM transaction machines in a retail store. I guess consistency in the types of machines would translate to a monopoly, and Lord knows we can't have that. But, I'm getting old and I only have so much space left in my brain for storage. Hence, the 'old dog/new trick' analogy is making a lot more sense to me these days.
Don't you agree, though, that it would make like much simpler if we could be uniform in SOME things. In California, the freeway lanes reserved for Carpools are called just that...CARPOOL LANES. In some states they're called Express Lanes, and in Tennessee they are called HOV Lanes. I just recently learned HOV lanes don't require High Octane fuel. I had steered clear of them since I use the lowest grade gasoline available. *lol* I finally figured out HOV means High Occupancy Vehicle. Now I'm challenged to discover how many people you must have in your car. A volkswagon full of clowns...three people, two. Me and a blowup doll? *lol* See, we aren't even uniform in that. In my old home state it's two, in some places it's three. I can just picture the committees that make up these rules. "Well, Let's show California we can go them one better. We'll require three adults, a child and a dog."
I guess I'll have to slow down and read the signs when I pass. You can't just assume you know the answer, can you? I'm beginning to understand why people just stay home. It's easier. Besides, I don't have a dog. :)
