“She’s a must to avoid/A complete impossibility”–from a Herman’s Hermits song
Boy, doesn’t that say it all about some people, the ones you definitely, clearly have to give a wide berth to or completely ignore. They are just not worth bothering about, are nothing but trouble, and who can even be toxic and destructive to you, others, and themselves.
Ah, the continuing wisdom of a long-forgotten pop song from the British Invasion of the ’60s.
