I'm glad that we as humans settled on the hand shake as a greeting instead of the whole ass sniffing thing.
And the there's the Sage Nod, which I use when dispensing advice. @bradlibum
@Meshelly There is still a lot of ass sniffing in the business world after the handshake.
@Meshelly I have noticed that different head nods are being used as greetings. Downward head nod is a basic greeting, upward head nod signifies you know/respect someone and a flailing head nod means holy crap it's that person!
