Say Hi Day is an annual holiday celebrated on June 11 in memory of Joseph Anthony Cinotti, a special needs teen who died at the age of 15. Cinotti made it a habit to greet everyone he met throughout his life, and his upbeat personality endeared him to his neighborhood. Say Hi Day is a public awareness campaign that aims to remind people that one simple word can improve someone’s day, bring a smile to their face, or shift their mood. A simple welcome can start a chain reaction of positive contacts and make all the difference.
