Today, in the United States, we commemorate Dr. Martin Luther King, Jr. Day. Today, kids in the U.S. might eat breakfast in pajamas. Their parents might shop a sale. Many will see (and welcome!) a day off of school or work. Some will use today as a day of service. It’s easy to let a day like today slide by without taking stock, without offering it the full measure of what a day like today deserves. So let us consider today.
