My heart was racing just reading about it. My dad and his side of the family were hoarders and I know what you meant. It was easy for my mom and I to chuck all the stuff after he passed. I’m the opposite of a hoarder, and my kids tell me that I don’t value things and memories connected with it. Ahem, a clay figurine you made when you were 5 that even you won’t want to display on your living shelf is going in the trash, son!
Kudos to you for trying to clean her bathroom. You have your work cut out for you. I hope you can outsource this to a cleaning company as that place will need industrial-strength cleaning!
