On apologies.

Don't do it unless you mean it.

"I'm sorry you were hurt by what I said," is not an apology.

Nor is, "I'm sorry you misunderstood me."

Those pseudo-apologies aren't fooling anyone. They're your passive-aggressive way of saying, "This is your issue, not mine. Don't be so sensitive."

If that's what you feel, say that. You'll be seen as an asshole, but at least an honest one.

For the record, this is a true apology.
