Pregnancy brain

So pregnancy brain is a very real thing. I was vacuuming our bedroom tonight with my new shark flex... it’s been working amazing since i got it a month ago. Well i stopped to clean the filter because it was full of dog hair... after that i moved to the bathroom floor and the vacuum was being very loud and not picking up worth a crap, so naturally i got pissed because it’s new so it should be working flawlessly... when i get done and shut the vacuum off i realized... I DIDNT PUT THE FILTER BACK IN🙃🤦🏻‍♀️
