Say you had met another couple you had a lot in common with and seemed to "click", and intended on catching up. At the time you met it was a social situation, dinner & drinks. The couple mentions a business they have and are quite passionate about recruiting people to join. It sounds like a pyramid scheme so we politely decline for other reasons (no time/no money etc). Then some time later, instead of planning the family catch up, one part of the couple asks if they can come and give a presentation of the business model. It's an awkward situation, not only is there no interest in the business (we honestly don't have the time either) but now feel slightly pressured. Because we want to be friends... so feel obliged to listen to the presentation... but we've already said it's not something we'd have time for/need/etc.... Not sure why they're asking to do this..... It seems redundant to submit to the presentation when there's nothing that would change our minds. But it seems rude to say "no you can't come over to do the presentation". Is there a polite way to say "we'd love to catch up, but without the presentation"? I feel really uncomfortable about it, and was quite surprised as they seemed to understand when it was initially brought up. I even joked about saying i hardly have time to keep on top of the housework let alone run a business from home... they laughed and seemed to get it, they moved on. Also my DH works 9-10 hour days with 2 hours a day commuting time. So this just isn't going to happen... We're not sure what to say though...

What would you do?
