A random act of kindness is a selfless act performed by a person or people wishing to either assist or cheer up an individual person or people. The phrase may have been coined by Anne Herbert, who says that she wrote "Practice random kindness and senseless acts of beauty" on a place mat at a Sausalito restaurant in 1982 or 1983. Either spontaneous or planned, random acts of kindness are encouraged by various communities.
