Nathaniel had loved both girls from the day they were born.
He knew Emily liked the crust cut from her sandwiches.
Lily hated it when anyone touched hers.
He knew which girl slept with socks on.
Which one kicked off every blanket.
Which one cheated at board games.
Which one confessed immediately.
Emily’s death broke him too.
