When you’re, say, reading a book about politics, and suddenly interrupted by a man who “hasn’t read that one” but would like to supplement your reading with all of the information he’s heard related to it–maybe this was last week, and maybe this was a book about Russia (okay, this is a specific scenario)–do as Maxine Waters does. Look him in the eye blankly, and state, over and over:

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

Reclaiming my time.

For the record, this is a clip from the House Financial Services Committee hearing on Thursday, and Waters is referring to a group of Democrats’ formal request that the Treasury Department disclose President Trump’s financial ties to Russia. It has so far been ignored.
