My friend Min has an upstairs neighbor who , every weekend, moves furniture around. And apparently from the sound of it, not just some of the furniture. Massive I'm about to move kind of furniture moving sounds. WE have speculated ( with a lot of ROTFLMAO ) what could possibly be going on up there. SO any ideas??
In the meantime - as she has 2 cats ( one slightly psychotic) I think she should get a cat cam and find out once and for all .
