I tried really hard to not make a list at the airport but then I made one and this is it.
  1. put on headphones and listen to other people's conversations
  2. watch people think they are falling in love
  3. fantasize about wearing the jet blue flight attendants outfit
  4. buy overpriced water
  5. hear announcement and then make eye contact w a stranger and shake head + grin
  6. Opt to walk instead of using conveyor belt. Feel superior.
