Well... I don't know. I'm not useful. I could be I suppose. I choose not to be beyond doing the things that need to be done around home... cooking, cleaning, walking the dog, etc. My personal opinion is there is no requirement for a person to be "useful". I just am. That's it. I try not to consume more resources than are required to live comfortably day-to-day. And I stay out of other peoples' way. I really don't want anything to do with people in real life; & I don't give a fig what they think. That's it...
