Give Satisfaction

Their main job was to be a private servant for the lady or master
of the house: assisting them with dressing, caring for their clothes, being a
general companion and even performing secretarial duties.

I didn't really realize that the "being a general companion" bit is actually part of the job description. So even canon Bertie thinks of Jeeves as his "companion." Why is this striking me as painfully adorable right now?
