From top to bottom
  1. The BFF triangle: "best friend is a tier, not a person" - Mindy Kaling
  2. Close friends: split into two groups of people with BFF potential and people that have maxed out their friendship level
  3. Coffee friends: people you would make time for sober
  4. Party friends: not friends you party with, but friends you would be excited to see at parties
