[Star Wars] Did Palpatine or Darth Vader have any, just like, friends?

Who did they hang out with when there weren't ruling the galaxy? What did they do in their free time? I bet Palpatine knits. Right? Who were their pals? Did they watch Star-Football on Sundays together? These are the important questions.

Palpatine had a small circle of people who considered themselves friends of his, or top advisers. Humans like Sate Pestage kept Palpatine's secrets and confided in him for many years. But it's debatable how much of it was a genuine, if professional, relationship and how much of it was Palpatine using them for different purposes, like he used everybody. 

Vader kept himself as closed off and alone as possible, except when he was forced to interact with others or when he tried to conspire. Like his time with Starkiller. No one hated Vader as much as he hated himself so in those dark times, no one suffered more or in as much silence as he did.
