As far as laziness, a lot of us aren't lazy. Procrastinators? Yes, since we do like to conserve our energy and frankly a lot of us work best closer to deadlines. My need for action comes out in various ways. Firstly, I'm not one for sports, though I do work out. However this is something I prefer to do alone. I am also an visual artist, and I don't like math much. Reading, repairing old gadgets and furniture around the house, traveling (locally or not), and listening to music are only some of the things I do alone.
Can't speak for anyone else here, but if I invite someone to join me in a personal hobby, that means I consider you a friend.
About your ISTP "housemaid," it sounds like she seriously hates her job and doesn't know how to tell you. I've worked as one, and I eventually quit because of how boring it became after a few weeks. But since this is a concern between you and your friend, I recommend talking to her about it face to face. If she IS an ISTP, either her Fe is terribly underdeveloped, or she's in a loop. Either way, good luck.
