I’m going to address the elephant that’s been in the room for most of my life: I’m bad at socialising. And it’s getting worse with age.
Don’t get me wrong, I have friends and can make pleasant small talk with strangers. Having said that, as an introvert, I hate small talk and will avoid it whenever possible. With friends, I am lively and opinionated and (occasionally) the life of the party. Although at work, I eer on the side of caution, I keep my head down and just get on with my work.
