Ice cream is half air, so 5 kg would take up anywhere from 2 gal (Edy’s or Dreyer’s Grand) to 2.5 gal (“slow churned” or cheap generics). Denser premium brands or gelato might take up as little as 1.5 gal. A 5 kg bucket that takes up only 1.33 gal would probably taste like frozen butter.
I agree with @cissycoxWhen Caulfield says “school makes adulthood less of a disappointment” he is being cynical: He assumes adulthood is no fun and suspects grownups make kids suffer through school only so adulthood will feel relatively enjoyable in comparison. But when Mrs. Olsen agrees “school makes adulthood less of disappointment” she means it at face value: Old people regret if they had only studied harder and gotten smarter their adulthood would have been more enjoyable than it is now.
