Read the excerpt from Lori's memoir project.

I look at the old photo and really consider it for the first
time. How did my parents feel that fateful day? Did
they express joy when they heard the news? My
mother grasps my father's arm tightly; was happiness
in that tiny gesture? My father's lips are taught and
compressed together-a face he makes when waiting.
What is it in their postures that makes my own heart
beat faster, willing the belief that their wishes had been
answered right after the camera clicked?
