NBC NEWS - Some presents are so priceless, they can't be put under a tree or stuffed in a stocking.
A mom in Maine got one such gift this Christmas and it's one that will keep on giving for a lifetime.
On Christmas Day 27 years ago, a young mother living under difficult circumstances gave birth to a girl.
"To me it was like I was given a gift, a gift that i was able to give to somebody else," Alice Gagne said. Gagne says she gave up her daughter for closed adoption, writing a letter to the new parents, hoping to explain her decision to her daughter someday.
"I would love to keep her but I'm only 17 years old and I don't think I am mature enough," Gagne wrote. "Every year on Christmas I will wonder what she looks like. I bet she will be beautiful."
Alice would see just how beautiful her daughter became, 27 years later to the day.
Amanda received that letter from her birth mom when she was 16.
Then Alice used an online service to track down Amanda this year, which has kept them in contact for some time.
Amanda made secret plans with her half-sister to surprise their mom on Christmas Day.
"I got to pick her up from the airport," Amanda's half-sister said. "I was the first one to hug her. It was insane. We had to take a selfie, of course, so we've got the first picture together."
"I'm thankful for you giving me to the great people and that everything turned out the way it did," Amanda told her birth mom. "I love you."
