I've noticed, over the years, an interesting language trait among the people I associate with in my work.

It involves making a statement, but using the intonation of a question, as in:

"I'm feeling a little tired today?"

or...

"So then I was really angry at him?"

I keep wondering where this comes from. My best theory is that there actually is a question implied by the intonation—something like "Does that make sense to you?" or "Can you imagine what that was like for me?" or just "Do you know what I mean?"

But I can't be sure. It may happen other places, but mostly I notice it in Santa Monica, where I work.

Which leads me to think it's a West Side thing?
