Note to husband: You know #3 on that Honey-do list? Yeah, the one about putting a cover on the outside heater air vent? Well, I think it's too late. If you listen carefully, you can hear a family of baby birds chirping away in the ceiling (or floor depending on where you are in the house) and while the sound is very naturesque, it's driving the cats nuts. (Plus, I hate to think what that vent will look like after the summer is over). Sigh...maybe next year.
