I never met a William Tenn story I didn't like.
"Project Hush" - if you've been in the military, it may take some real internal struggle to understand the humor. If you don't like the military, it will probably just make you angry. If you are on some other plane, then you might give a smirk, sneer, smile, snicker, or laugh out loud. How true.
"Wednesday's Child" is horrific. I'm sure Lovecraft would have enjoyed it, and worked a sequel for it. The tiel piece, "The Human Angle," is so short, but also a bit terrifying.
"The Discovery of Morniel Mathaway" is eerie. Reminds me of a story I read about Shakespeare or not Shakespeare.
"The Servant Problem," "Party of the Two Parts," and "The Flat-Eyed Monster" are the alien tales, and right Tennish, they are, too. They were my favorite in this collection.
The story, "A Man of Family", reflects contemporary, and presages later moral/anti-moral arguments about absolute values, [alleged] over-population, the value of life, abortion, euthanasia, end of life with dignity, definition of family, responsibility of parents, attitude towards children.
