What a perfect mesh of milestones: Mothers Day and graduation, when a parent’s pride intersects with a young person’s ascent into the world as an independent adult. Families are gathering today to celebrate the mothers, grandmothers and generations of nurturing, loving women who gave them the love and guidance they needed to succeed. Those mothers will shed tears of joy in days to come as they watch their grown babies accept their high school and college diplomas and enter the world.
