The friends library is well known to have lots and lots of dependencies, and can be very rough to work out the multiple things available to have a working friends class.

  #require loyalty
  #require compatible
  #require sincerity
  #require compassion
  ...

You can try commenting out some of the required packages, but the quality of the friends class does become questionable

I'm so old that I can remember when Dale Carnegie released the friends package and its sneaky, buggy dependency on the LoveOfMoney package.

on edit: the old it's / its problem got me.
