We were very inconsistent regarding these rules. Personally I prefer no empty lines around blocks, clases, etc... as recommended by the Ruby style guide [1], and they're the default values in rubocop, so those are the settings I'm applying. The exception is the `private` access modifier, since we were leaving empty lines around it most of the time. That's the default rubocop rule as well. Personally I don't have a strong preference about this one. [1] https://rubystyle.guide/#empty-lines-around-bodies
