I am another introvert who finds it hard to make friends. I got bullied a lot when I was younger, and put down by various relatives, so I find it a bit weird when people actually seem to like me!
My dogs, on the other hand, are complete and utter social butterflies. They are very friendly and attract a lot of attention when they're out and about. Dog walks take forever because people like to compliment my Collie and reminisce about their grandparents' collies. They look very shocked if I happen to mention that my smiling, relaxed collie is an experienced sheepdog who thinks nothing of herding 100+ sheep or cattle by herself!
I am in my 30s. I have work friends and I speak to most of my neighbours. In real life, I have about two friends. One is of a similar age and lives in Canada (I'm in the UK) and the other is a generation older and lives a few hours away.
I am cheerfully, and permanently, single. No thanks, I don't want your sympathy or a date set up for me with someone that you know. I am happy on my own, and I really don't mind going to interesting events by myself. In fact, it's preferable, because I don't have someone huffing and complaining that it's boring next to me! I work on a farm, which my family finds embarrassing, so they lie about my career, but I'm much happier than I was when I worked in my former respectable role. My job stuns most people, because I am small, female and I like driving tractors with wheels that are taller than I am. Even worse, I can drive a JCB. Today was a good day, because the manager was off and everything at work went well.
I find it a bit tricky to fit things in after work due to my hours, so I end up trying out hobbies and never going back to them! It is easier to entertain myself at home, so I enjoy reading and knitting, and I'm trying to learn the art of gardening but hate weeding and all about sewing machines. One day, I'd like to be a bit more self-sufficient, so I have a lot to learn! I have a few one-day courses of interest lined up this year. I also like writing, OP, but I am unsure as to whether or not I'll ever finish a book, or have the confidence to publish it!
Good luck with your new job!
