I'm an optimistic skeptic. So I have my own explanations for strange things I might happen to see, and then hope I'm wrong.

I was standing outside my North End home Wednesday night around 7pm, when I noticed four red, flickering lights floating across the sky. Before I could pull my phone out, they disappeared. But slowly, other lights soon appeared, and I was able to catch one of them on my camera.

Turns out, I wasn't the only one to see these lights. Check out some of the calls to "Mid-Day Live" this afternoon.

This caller says she saw the strange lights last month, too.

The best explanation I've heard so far is that the lights were the popular Chinese Sky Lanterns.

What say you? Are we alone?
