Tell me about it: a rant.

You know that thing where people say tell me about it when they actually mean don't tell me about it - and then go on about it themselves for half an hour?

That.

Word To Use Today: tell. This word has been pretty much the same for a thousand years. The Old English form was tellan. It's related (third cousin once removed) to the Old High German zellen, which means to tell or count.
