Have you ever noticed that some people avoid using question marks in their emails? They’ll say: “Can you call me to discuss.” Or: “When should we meet for dinner.”
I think they’re trying to signal power, but these linguistic bids for dominance never fill me with respect. They just get my back up.
Some people do just the opposite. Not only do they use question marks but they come right out and admit uncertainty: “I could be wrong, of course. What do you think?” They use exclamation points! “Great to see you today!” They even sign off with “xo” and smiley emoticons.
