Above, Jerusha Willenborg of Wichita, Kansas's Mueller Elementary. Below, Barry White Jr. of Charlotte, NC's Ashley Park Elementary School. It reminds me of my daughter's wonderful second grade teacher Ms. Foskett who at the end of every day took a moment to say goodbye to each student individually however they preferred, with a verbal "bye," hug, handshake, simultaneous clap, high-five, etc. I liked watching this ritual because you could really see in the kids' eyes the connection Ms. Foskett made with each one of them.
