There are actually rules for when and how to fly the flag at half-staff. The President and state governors can order flags to be lowered to honor national heroes, veterans, and even Tragedy victims. It's pretty cool that there's a whole system in place for showing respect through flags!
But here's a fun fact: did you know that the flag is only supposed to be flown at half-staff until noon on Memorial Day? After that, it gets raised back up to the top - symbolizing the living taking over from the fallen. It's a pretty poignant tradition!
