+1 for most of the “why aren’t you married ones” – used a few up to when I got married (9 years together at that point). Actually, that reminds me of a classic when my now-wife’s housemate said with quite a superior tone ‘When you’ve been together as long as my husband and I have been…’. Then we pointed out that we’d been together 2 years longer than they had been.
Thing is once you do get married, people then ask when you’re having kids which IMO is much worse. For a start, I’ve seen friends who are having trouble with conceiving/miscarriages asked…
As such, I did famously once stop a particularly annoying woman in her steps when I stated loudly that ‘We can’t have kids, it’s devastating, we’ve been trying for ages, etc’. None of it true but the look on her face and the looks at her from everyone else (who also didn’t know it wasn’t true) were priceless 🙂 I don’t think she asks people that anymore.
