The Strength a Single Word Can Have

I had a good day at work today, received one compliment from the boss on my writing skill, helped another person write an e-mail (took a razor to it, is more like it, though by the time I'd finished, I still thought the four short paragraphs didn't say much of anything, at least not what three short paragraphs could have covered just as easily), kept busy, kept communicating, and got on a couple customer's nerves (Judy and Racquel) -- hey, I'm just doing my job, y'know?  Gotta follow-up those e-mails with phone calls. 

Anyway, the sun was out all day, which always helps.  And I finished another story on EP.  Near the end of the day, my boss said he didn't like the subject line I gave an e-mail:  "Please ensure these invoices have been paid," or something like that.  He thought "ensure" was too strong a word to use.  He wants to use "check" from now on.  Well, the person I was writing to had seven outstanding invoices that weren't paid!  Hello?  Anyway, the e-mail had already been sent, so tough.  My boss doesn't appreciate the strength that a single word can have.  That's why he hired me.
