Elmo is mailing his first letter, but he�s worried something will happen to it, so he follows mail carrier Jasmine to the post office to see what happens. There, he sees how everyone�s mail gets sorted to go to the right place. Elmo and Jasmine make stops to deliver mail to their friends and, along the way, Elmo learns that mail carriers are everyday heroes who help us stay connected to each other. Guest: John Batiste
