The Elder got a haircut.
The Younger got a bike.
Both of them found many new ways to fight with each other.
They fought over who got to water the garden.
They fought over not wanting to share anything.
They fought over who got to give The Youngest her nuk.
For myself, I arrived at a new level of irritation, and lost it a little with my darlings.
They'll come up and bloom regardless of whether someone likes their meal, or can stand to be in the same room with a sibling, or allows the cumulative effect of many tantrums and systematic sleep deprivation push them over the edge.
