Not normal mess no but actually dirty then I judge.
Like dirty clothes everywhere, dirty floors, lots of dirty dishes, smell of cat pee that kinda thing is just gross. Sorry of it offends anyone but I am a clean freak and I just can not understand how someone can have children crawling around on floors so dirty that their clothes are black and smelly dishes everywhere. It's not hard to vacuum a place or use a mop. It takes 10 min to do dishes 3 times a day.
But toys on the floor, laundry not folded, bed not made that stuff doesn't bother me.
