STORY TIME: I'm pretty sure everyone has at least ONE bat story.
It was summer, several (many) years ago. DH was sitting in his chair in the living room, minding his own business. Reading a book. It was evening...8 pm? 9 pm? I was in the kitchen, also minding my own business, reading the newspaper. Enjoying a bowl of ice cream because being summer, the weather was hot. I was having a problem with my eyes, though. I kept noticing a dark swirling as I was reading the paper, but it was very intermittent. I'd look up - things were fine, then I'd look down and dark swirling would start again, then the whole scenario would repeat. Finally, one of the times I looked up I saw that something was flying around the room. At first I thought it was a bird, but then the "thing" landed on the small kitchen speaker up in the corner at the ceiling. Holy Mackerel Batman!! (Hah, notice the pun?) And, yes, I am a girl at heart, so of course my first response was a bit of a scream. Then another scream for DH who, as many men would do, said "whaat?" I continued screaming: THERE'S A BAT. THERE'S A BAT. THERE'S A BAT. And again, as many men would do, he said "what do you want me to do about it?". I'm thinking to myself: Uh...wtf? This is why I got married? I did a little more panic-ed screaming at him, until he finally came into the kitchen... to make sure it was a bat and that I wasn't imagining things. Since, you know, ladies don't always understand these wildlife things. Apparently. Uh huh. Then he got a light jacket out of the closet and managed to fling it over the bat as it was whirling around the kitchen.
The poor thing was lobbed out the front door, jacket and all, where it eventually made it's way to freedom. We assume that it flitted into the house from it's normal roost by the front door when the dog took a little too long to come inside.
I no longer say "Oh, look, honey - there's a bat living by the front door. How cute is that?"
