['I recently found the baby book I made for my baby when she was born... she just turned 21.', 'Congratulations on the good raising of the kid! I bet you were just flooded with all kinds of memories.', 'Yeah, it was amazing to see all of the little firsts that I wrote about.']

I found the baby book I made for my daughter when she was born. She's 21 now. It was nice to read all those things about her as a baby.
