While you’re on a second date, your conversation should start getting deeper and deeper (as well as on your third and fourth dates). This is not just superficial conversation; you should be asking questions and discussing more in-depth topics. To find out if you enjoy the same topics, you can mention them and see what reaction you get: A blank stare? An eye-roll? A passionate debate?

If you like world events, mention the Iran Deal, Greek’s economic collapse, or ISIS. If you enjoy science, then mention global warning or stem cells. If you love entertainment, then bring up the recent Emmy nominations, Amy Schumer, and anything else trending. If you’re passionate about politics, then broach the topic of Donald Trump and then the dozen other Republican candidates. If current events get you going, then bring up the topic of racism and if police are using unnecessary force. And of course, there’s sports… but that’s an easy one.

You may find that you cannot see yourself with someone who doesn’t read the newspaper, or someone who only gets their updates from TMZ, or someone who’s politics differ too much to understand, or whose schedule revolves around SportsCenter. Differences are good, but you need to have respect at the core in order to have a healthy debate. If you do decide to enter into a debate during a date — which is fine — be respectful and don’t hurl personal insults or allow it to upset you. If that happens, then you likely have your answer about the fate of the date. Remember that looks fade, but the ability to have enticing conversation can last forever.
