There is a time for everything, and a season for every activity under the heavens: Ecclesiastes 3:1
When Caterpillars did not transform to Butterflies. Butterfly did not want to associate with caterpillars incapable of flying. Butterflies that feed on flower nectar were disgusted with food habit of caterpillars feeding on green leaves. Mr pillars were scary and ugly and could not understand ways of Mr Flies. Mr Fly was happy that he had transformed from the weak ways of Mr Pillar.
