I am 70 and I have lived alone for the past 20+ years. Until last year I was working so I didn't mind being alone. Then after retiring last year, I rescued a little female poodle named Pearl. She has been the best companion and I believe we saved each other. I often think about having a human companion but I am so used to doing what I want, when I want, that it always seems like too much work. I am invested in my family and grandchildren, and some dear friends. That seems to be enough. No situation is ever perfect all of the time.
