reread, in effect, having read the stories in other collections. asimov still gets a crack out of me when the normal, non-teleporting door to exit their home is described as "For emergency Use" — probably a bigger one. wit, before any other word, was the constant virtue i recalled of reading his works, getting possibly too snappy, four in this collection from child's rebellion in the face of encroaching artificiality, to academics plagued by a phenomenon simply taken out of dreams, to cosmic horror from the sanatorium and the atomic lab, to a civilian fighting an alien hijacking alone out of the passengers. if i can place it now, an inspiring basis of his writing would be that it is an individual who has a relationship to technology at any given time, people who find a need to understand their problems. the easiest light reading in a while for me.
