No, really, I could. But I don't.
What the hell am I talking about? That curious, annoying habit it seems many people have when they truly don't care about something to say "I could care less." I'll sometimes reply "So, that means you care at least some, and therefore could care less?". "No, I mean I don't care." comes the usual reply.
Damnit! The proper saying is I couldn't care less! The first time I heard the phrase, properly, I was very young. It was probably my Mom saying something like "I couldn't care less if you don't like spinach, eat it!". I continued to hear the phrase, usually from my Mom or Dad in a similar context, for the next 10 or 15 years. Then, some time around 1980 or so, I started hearing people say "I could care less."
Do your part. If you hear someone say "I could care less", challenge them. Make them say it right.
End of meaningless rant.
