The tradition of flying flags at half mast dates back to the 17th century, when it was a way for ships to signal that they were in distress. Today, it's a way for Americans to show respect and solidarity, kind of like a national moment of silence. But instead of being quiet, we lower our flags to half mast, which is a pretty powerful symbol.
Think of it like a big hug for the nation, where everyone comes together to support each other in a time of need. It's a reminder that we're all in this together, and that we care about what's happening to our fellow Americans. And just like how you might wear a black armband to show respect for someone who's passed away, flying a flag at half mast is a way to show respect for the nation.
