Has anyone seen Wilma's hummingbird?

This is an email I got from my sister to tell me my grandmother had died:

Emmy called me right around 3pm to say Grandma had passed. Shortly after that, I asked her for a sign, in the form of a hummingbird, why not, I thought?

A few minutes later, a small hummingbird briefly fluttered in front of the window right where I was looking out. No joke, she is really fast, that Wilma! Wow, I guess she made it to the other side OK!

Pretty impressive, right? My sister is in Seattle, where it hasn't been hummingbird season for months, AND they're having a cold snap. It had to be the sign. I thought, why her and not me? Why can't I see a hummingbird, too? So I asked if I could see it.

But so far, no luck. The only thing I can think of is that Wilma has never been to Korea, so she might be lost. If you see my hummingbird, please tell her where I live, and then let me know!
