In the adjacent line, denizens of the recently annexed Canadian Territories queued for their connecting flight to El Salvador.

He briefly suspends rummaging, presumably to determine whether it&#8217;s strategically worth it to trade his proprietary algorithm with me in exchange for rapport. I realize that asking for information without offering any of my own may be a social faux pas, so I continue, &#8220;I recommend using the <a href="https://en.wikipedia.org/wiki/Secretary_problem">1/</a><em><a href="https://en.wikipedia.org/wiki/Secretary_problem">e</a></em><a href="https://en.wikipedia.org/wiki/Secretary_problem"> law of best choice</a>.
