Dad is 81, he shares a bathroom in the hall. We have our own bathroom. It has been getting worse with the messes. Mostly the urine missing the toilet. The other evening while making dinner I had to clean up the large puddle floor in front of the toilet (while I was prepping dinner)? He doesn't wash his hands and I have found poo in places it shouldn't be. It is not a cognitive issues, more of lazy. The smell is starting to really get to me since my wife and I keep a clean home. Don't get me started on my son in laws nasty smelling room of unwashed clothes. Between both of their rooms the smell is horrible. Neither my dad or my daughter were raised that way and I do speak up. The issues with the missing the toilet is getting to me. How have others brought the delicate subject of aim and habits up?
