A man I work with didn't get married untill he was in his early 30's. He was raised by a very strick step mom and was a clean freak. When he would have the guys over to watch sports he would have the dust duster cleaning crumbs off the floor and couch from the guys eating chips. Well he married a woman with three small children. They were living with their dde during the dating but came to live with them when they got married. He came to work freaked out everyday by what the kids did to his house. He followed them around with a bottle of spray cleaner and a rag for the first year and then gave up. He was horrified that " they pick their nose and wipe it on the wall!" All of us parents were like ya we know.
