From time to time, words kind of strike me as odd.
Maybe it's because I work with them for eight hours a day, and so they start running together. (Not, unfortunately, a good thing when you're trying to proofread something.)
Maybe they're always odd, but it's only some days when they allow themselves to be seen as such.
Today, as we near the holidays and the food festivals that they are, I am left wondering why it is that "guinea pig" is the animal left being used - nominally, at least - as a... well... lab rat.
Why not rats? Why not voles? Why not hamsters?
Like I said: odd.
