Mind Games

I keep hearing this noise. One that sounds like a HUGE Horse fly is buzzing between the blinds and the window.

YK, the kind of fly that could suck you bone dry in about 2 seconds.

So after staring over there for a while, I realize it's not so much a fly in the window, but J's Mylar Dora balloon rubbing up and down the wall thanks to the air coming out of the a/c vent.

So KNOWING this now, why, every time I hear that sound, do I still immediately think there's a fly in the window?

I really should move the dang balloon before it drive me bonkers. LOL
