The "Hello Spirit" is a cultural practice engrained in Stanford's history dating back to the late 19th century — it embodies the unspoken bond between members of the Stanford community and highlights a comfort in spontaneous interaction that lays a foundation for lasting relationships at Stanford and beyond. Authors van den Dale and Perper argue that our community should reconnect with these roots to foster a culture for future generations to appreciate. They write, "Our greatest challenge now is to revive the oldest tradition of the Farm...Just say hello."
