Seeing it for what it is isn’t being miserable though it’s being realistic.
So for the onlooking public they’re seeing a video, and finding it entertaining. Fair enough, most of the people on the internet aren’t going to look past that.
But for the people selling the house they have an estate agent who is gaining a name for herself while using them to do so, and meanwhile distracting viewers from the fact the house is a pigsty. Something which will become abundently apparent when people actually go and view the house and realise that the video was just a distraction.
I’ve viewed houses which were in such a state that I couldn’t tell you a thing about the house. Look at that video without the sound on and it tells a vastly different picture.
