If you've ever lost a toy that your child is very attached to, you know the lengths you'd go yourself to try to get in back.
But you'd rarely expect others - let along a stranger, to put in that kind of effort.
So it was extra special for a family who recently flew into Dallas when a Southwest Airline employee went to infinity and beyond to return Buzz Lightyear to his best buddy, little Hagen.
It was only when the family had picked up their rental car and began driving away from the airport that they realised Buzz had been left on the plane. While they thought he was lost forever, Ramp Agent Jason was on the case.
In a plot that could be straight from a Toy Story film, the airline explained in a Facebook post how the agent helped Buzz find his way home.
After finding Buzz when the plane terminated in Little Rock, Arkansas for the night, he did some digging to find who may be the owner.
"Jason knew someone was missing their friend badly, so he began some investigating to discover who he belonged to. Soon, a name written on the bottom of the boot caught Jason's eye: 'Hagen'," they wrote.
"With the help of Beth, his Coheart, Jason learned there was only one 'Hagen' who had travelled on that aircraft that day. Instantly, Jason came up with a plan..."
"A few days later, Hagen and his family received a special surprise in the mail. Not only was his buddy returned, but he arrived in a hand-decorated box, complete with a letter describing his mission at Southwest Airlines, and pictures to boot."
A note included in the package detailed the mission.
"To Commander Hagen," it reads, "I am very excited to return to you upon completing my mission. I was able to explore the airport and spaceport in Little Rock, Arkansas while I was away and I have included photos of my adventure."
"My journey has taught me a lot but I am so thankful to return to my buddy."
As Hagen's mum Ashley told the airline, her little boy was beside himself to have his friend back home.
"There's definitely not enough good in this world, and for someone to take the time out of their day to do that for strangers means the world to us," she said.
