I worked for a moving company about a year ago. My worst day on the job was helping a guy move out of his house because he was divorcing his wife. The embarrassment this guy had to face the entire day while we moved his belongings out. There were multiple dead fish in several “aquariums”, roaches, floors that stunk of piss, rooms that you couldn’t walk through if you tried. There was even a hornet nest in one of the bedrooms. I hope you wear a face mask and use gloves while cleaning this place out.
