Better Left Unsaid

Therein lies the rub, there are a great many things that are better left unsaid. It's like the person who prefaces his statement with "not that it matters but..."

So then he's telling me that it does matter since he's now bringing it to my attention, right?

Or the person that says "the pronunciation isn't important but I say...", which means the pronunciation does matter since you've pronounced it for my benefit.

So let's say what we mean and dispense with what we say, shall we?
