I have an ex that seriously makes my skin crawl (as I'm sure most people do!!) there were many things that just didn't sit right but perhaps the worst thing was the poo towels!
When doing laundry I would always come across one or two towels that had massive skiddys on them...
For that to happen it means he would had to have had a poo, not wipe (at least not properly) shower, but not wash and then wipe his shitty arse on the towels
