How's this for thoughtful?
Starting with the STS-26 return to flight mission and continuing until the end of NASA's manned program, the Shelton family would send a bouquet of roses to Mission Control. One red rose for each astronaut on mission, and one white rose in remembrance of those who had been lost.
Apparently it took NASA a while to figure out who was sending them. A simple but thoughtful gesture that probably means a lot to those who hold life and death responsibility over astronauts riding perhaps the most complicated gadget ever manufactured.
Also, as a parent I've got to hand it to the mom and dad - setting an example like that is top shelf parenting technique.
