These preschoolers start their day by choosing between a variety of fun greetings for each other after their teacher wanted to encourage positive interactions. Every morning, teacher Kali Lovgren has her class begin by lining up by the ‘greeter of the week’ and choosing how they would like to be greeted that particular morning. The four-year-olds use a chart to choose between a hug, handshake, fist bump or high five on their way to class and the morning greeter will greet them accordingly. Kali, who teaches at Lone Tree Elementary in Lone Tree, Iowa, shared the adorable video on social media charming thousands of people happy to see the kids learning a valuable lesson.
