Small boy, big joy

Met a woman yesterday with deep smile lines
etched in her face. She was so, so excited
pushing her son in the swing. I asked how old he was.
She said 22 months. I tried to hide my surprise—
from his size I would’ve guessed under a year. Then
she smiled even wider and said,
“But we just got him two weeks ago.”
“Actually,” she gushed, “it’s been 18 days.”
