I’ve been greeting my classes with “Hi guys” for over 40 years. I don’t know what I’d use instead if there were complaints. Since I’m neither a politician nor a Glaswegian ice cream vendor, “Hello folks” doesn’t feel right, and if I use the obvious “Greetings, people of Earth” it will reveal too much.
(Edited to change “30” to the more accurate “40”. Yikes!)
