I've lived alone for so many years that to have to be around other people 24/7 would drive me crazy. I'd probably be driven to throttle someone. I have two sons, but they don't live close by. One is in Indiana, and the other lives about two hours away. I don't have any grandchildren which is fine with me. I raised my two alone, and did my bit for motherhood, and I don't want to be anybody else's mother/grandmother at my age.
I'm the last one left in my family. My brother's family lives over two hours away, and I usually visit them because it's easier for me to do so. I love my privacy...can't stand it when the phone rings, or anybody knocks on my door. Thankfully it's usually only the mailman or the maintenance guy who is on the other side of the door. I can count my close friends on one hand. Other than FR, I don't do Facebook or any of the other social media sites. Basically, I don't like people...most of them, and don't want to be bothered with them. I get all the socializing I want on FR, and at my doctor appointments. I've been called stand-offish, but I worked in uniform for 25 years in NY's prison system, and the job will do that to you. There is only one co-worker, out of all the people I met over the years that I keep in touch with. Met her in 1980 at Auburn Prison, and we've remained friends ever since, even after I transferred to another prison near home, back in 1983. I meet her and her husband once a month at Turning Stone Casino, which is only about a 20 minute drive for me. We eat at the buffet, and play slot machines, then we leave. It's more than enough entertainment for me. I'm an avid reader, and a history buff...and that's how I like spending my time.
This might surprise you but, your post made me smile. I often feel much the same way. I guess I'm not quite as done with people as you are, but... I'm sure getting there.
I don't mind being alone. I enjoy it. I travel a great deal for work. So, I often spend many hours by myself. I'm the most entertaining person I know. :-) SO MUCH to read, learn, listen to, watch.... There is an endless supply. As long as I have a couple of good friends to talk things over with, I'm good.
That said... I'm still in the new grandparent phase, and I'm LOVING it! Wife and I had two sons... Now, my oldest son has two daughters. Christmases are VERY different now. All dolls and dresses.
