"Perfectly contented" and "Pleading Child"

[Vaysburdn]

This paragrath from story Amy Tan "Two kinds".Last paragrath:"And for the first time,or so it seemed,I noticed the pieceon the right-hand side. It was called "Prefectly Contened".I tried to play this one as well. It had a lighter melody but the same flowing rhythm and turned out to be quite easy."Pleading Child" was shorter but slower;"Perfectly Contented" was longer but faster.And after I played them both a few times, I realized they were two halves of the same song."
