The art of being agreeable enough that nobody remembers you were there.

means The quality of being pleasant — agreeable, nice, easy to be around, without any particular strength of character.

from From 'pleasant,' borrowed from Old French 'plaisant' (pleasing, agreeable), the present participle of 'plaisir' — to please. That traces back to Latin 'placere,' meaning to please or be acceptable, the same root that gives us 'placate' and 'placid.' Add the native English suffix '-ness,' which turns qualities into abstract nouns, and you get a word literally built to describe the state of pleasing — of causing no friction at all.
