I was thinking, you bought these how many years ago, dear? But while he kept looking, I did the not-a-guy-thing (Richard later said something about almost compromising his masculinity and trying that himself–we were having a good time teasing each other) and I found someone who looked official and asked.
Oh, sure, we have those! And the guy disappears in the back and comes back out loaded down with like two dozen of the things, his face almost disappeared behind them.
He tells us they’re ten bucks. Richard, who’d found me by then, goes, Nah, I can get’em with AA batteries for that much.
Oh. $7.99, then.
“Do these things really work?”
Yeah, they do! I have all this wool around and knit and yeah, those things, they are really useful!
The guy grins. “Two bucks!”
Our old ones had had arc attacks (do not hit the furniture when flailing around with one, and I’m not talking electric arcs) and they’d died one by one. We bought seven. Bugs shall fear me again.
