The questions answer themselves. The planting of worry in the mind of
another is heartless, cruel, unkind and selfish.

Another question naturally arises: If this course of action is
selfish, and the worrier really desires to be unselfish, how can he

morning to night, and whether this seems "nagging" to her or not,
there would be a unanimous vote on the subject were the child

Then, if John fails, take the hat and lock it up, and _let it
