How accepting is your 'circle' of those who go against 'the norm'?

I'm a married child-free person. We don't own a house, we move around a lot (lived in 6 countries the past 14 years), my partner changed career five years ago to better suit his desired work life balance, and neither of us earn more than the average income. We live in the UK but are originally from Canada.  We don't have mortgage expenses or kids so after investments and savings, our spare cash goes towards traveling, even if it's just local exploration. Both of us have a lot of flexibility because that's how we built our careers, so we can go away midweek instead of weekends, in the off season instead of school holidays, etc. Even just having this flexibility saves us a lot of money. We can go away when the weather forecast says it's going to be nice and not when the kids are off school.  People like to say they are accepting of a child-free lifestyle, but when it comes down to it we get a lot of "must be nice" and grumbling resentment over the fact that our house is clean and nicely decorated, we never get sick, we do nice things on our holidays and have never once had to end a trip early because one of the kids got sick in the car or fell off a rock and broke their arm. We go on long walks on the coast or in the country without anyone complaining they're bored, eat nice food without worrying about someone wasting a meal, and generally just do things the way we like.  We don't share on social media anymore and we downplay everything because while we've been having a peaceful, calm, restful holiday break, everyone we know with kids spent two weeks with superflu enduring temperatures of -35 (family lives in Canada). It just doesn't fly to talk about how great a time we had roaming the Cornish coastline and eating cream tea, it's insensitive.  So basically, if you know a child free couple who don't post on social and keep mum about what they did on the weekend or during the holidays, it might be because they're worried about how living an intentional life will come across.
