I finally have one!
Over the years, I've been approached by friends and colleagues selling whatever--Princess House Crystal, Pampered Chef--and never had any trouble saying no since I never needed or wanted any of that stuff, but now my next door neighbor has joined the MLM crowd, selling 'natural cleaning products.' They've been nice enough neighbors, but we have never socialized so I was surprised when she invited me to a 'reception' that she was holding one afternoon after handing me a postcard showing the company's wares ("Thanks, but sorry, I have plans!"). Later she approached my husband while he was washing his car in the driveway, asking if he wanted to try out a 'silver-infused cleaning cloth' that she had in her hand.
DH is a sweet guy and said sure and thanks, and gave the windshield a swipe, but then noticed she was still standing there. He asked, "Um, are you giving this to me?"
"Oh, no! It's from (whatever brand) and I'm selling them," she said with a big smile.
"Oh, okay. Here. No thanks," he said as he handed it back.
When DH--who is an extraordinarily generous guy--told me about this exchange, he said, "You know, after all the free passes I've given them to (very famous and costly theme park where he works, literally thousands of dollar's worth of passes), she couldn't give me a free rag? That's nuts."
I don't think she'll be trying to sell us anything else for a while, and those free passes they've been getting once or twice a year? Yeah, they lost those too. Good luck with that MLM!
