For the most part, we tend to believe that if something doesn't affect us, it'll take a pretty strong argument to make us worried about it.
However, as anyone who's made it clear to their family that they don't intend to have children will tell you, there are no shortage of people who will think they need to be talked out of it. It's not any of their business and people can be just as happy without children as with them, but that doesn't really stop them.
And perhaps the worst part of this dynamic is the fact that friends and family members who are this concerned about whether other people have kids or not are rarely willing to let it go after they've already been told it's not going to happen.
That was the situation one woman faced and when she tried to play off any impending awkwardness with a joke, it seems it couldn't have gone worse.
