How do you relate neglected people?

Dictionary: Wikipedia. Com – neglect v.. 2. 2. What type of food should I eat to keep my memory alive? To be remiss in the care and/or treatment of
one’s family, to neglect one’s appearance.

If “rusty” is idiomatic, you might find “Nichted” is more literally appropriate for the examples given, or “Melody” is better for any situation. As noted in the accepted answer, when metal objects are neglected (particularly outdoors), they become rusty, which is the source of the idiom. I

know I should and I would not attempt to argue, but if someone is doing something stupid, the answer is so easy.
