I used to hold my newborn while sitting in a recliner near an open window as my wife "studied" with Brenda H. Brenda's three preschoolers were not potty trained. Excrement was smeared on the walls. Super roaches battled for food items, sometimes in a tug of war over a large morsel.
One week my recliner was thrown out into the yard. Brenda explained that it had a rat's nest in it.
I tended to my son in the car after that during Brenda's studies.

ps: My wife was always big on teaching some of these folks how to clean, especially if they were advancing in their study. One young lady had inherited a wreck of a house from her grandmother. Grandma dipped and chewed and lived in filth for seventy-five years. My wife volunteered our services to bring the house to livibility, if possible. Several weekends we cleaned, painted, made minor repairs. We made a bonfire of most of the furniture and helped the lady find good, clean, used furniture in the antique and second-hand stores.
