Ever noticed that in email conversations, the responder tends to mimic the style of the initial email? They take note of whether the address was to a full name (i.e. Ms. Daniells) or first, they mimic the language and conversation style, they even often copy the salutation at the bottom of the email (i.e. Sincerely, Best, Loyally, etc.).
I guess in this hyper-connected internet age, that’s the responder’s way of picking up on ‘body language.’ Only, instead of observing one’s physical body, they study the body of an email.
Like I said, random observation…
Monkey see, monkey do…e-mail style.
