Not sure why someone downvoted you. The mother of one of my classmates as a child was absolutely psychotic (still is) and she insisted on having locks on every cabinet, not just to keep out the nannies (though I think she paid premium prices for all of her nannies to be Harvard-educated), but to keep out the children, so they couldn't snack without permission. All of her children got fucked socioemotionally from her insanity.
