The rule of the day relates to how sarcasm should have its own font just so it’s perfectly clear that the person writing the sarcasm is actually being sarcastic.

Have you ever read an email (or a newspaper article, Internet article, magazine article, etc) and wondered if the person writing it was being serious or sarcastic?

I’ve read plenty of emails from people who I don’t yet know very well who try for some reason to make a joke and sometimes I can’t tell whether or not they’re actually joking or serious. Sarcasm only works when it’s obvious and when it’s applicable to the situation.

Sometimes it’s difficult to convey sarcasm unless you put an annoying smiley face after every incident just to make it patently obvious to readers that sarcasm was intended.

Moral of the story: Watch what you write and how you write it whether in a work setting or when applying for jobs. Sometimes people try to get a bit too cute and make a joke and might not realize that the person at the other end actually reading it might not get the joke.

Or worse, they take the comment the wrong way and you pay for it as a result.
