Non-parents just don’t understand
If you’re not a parent, you don’t know what you’re missing. There’s nothing like holding onto your newborn for the first time while wishing that no harm comes to them. However, even the most loving parent can have one of those days where a screaming, jumping child is too much to handle. This is something that childless people will never get.
Or maybe they do get it from our constant complaints on social media. In fact, maybe they have a good idea of how frustrating raising a child can be. That’s probably why they won’t have kids in the first place.
