Is that on the inside or the outside?

Is that fly on the inside or the outside of the window? I really can’t tell. If it’s on the inside, then it’s going to walk its excrement-encrusted legs all over my food before vomiting its digestive juices on whatever’s around and then sucking up the remains. Its eyes are also the size of its head; that’s yet another reason to love flies.

I find that it’s inside the window as I try to catch it. It’s just proving why flies have been around for 240 million years; they’re survivors. They’ve been around 100 times longer than humans and this one is intent on proving that to me.
