Ever pause while writing, and consider the em and en dash, or their little partner, the hyphen? Reading about them doesn't ease my anxiety, especially when I realize that someone, somewhere, has made a decision that there shall be no spaces, except for the poor hanging hyphen. Then, only a space on the right. Really?
I personally don't like a dash that touches an adjacent letter. The hyphen seems normal, and doesn't catch my attention. The others just don't feel right - like too many exclamation points!!!, or the USE OF TOO MANY CAPITOL LETTERS. I know, I'm a little strange, but I admit it, so it I can't be held accountable. I hate arbitrary rules, or what I see as arbitrary rules. It is comforting to know that James Frye is alive and well out there to provide a balance between what is important, and what isn't.
