Am I the only person that didn't know there's a difference between a hyphen and an em-dash?
In some ways, why? The hyphen is-right-there on my keyboard — but no, I'm not allowed to use it, it has to be a dash — and in pairs only! What-the-fuck!
Is it a native English speaker thing? We never seem to know how the language actually works - also what the hell is an insert key?
Oops I did it again!
