I info-dumped more in the past. I remember I’d give my babysitters big lectures about animals when they drove me in the car back in middle school. While they all seemed mildly interested in the subject, seemed to enjoy hearing me talk about it, in hindsight I kind of feel like I was “wasting” my knowledge on people who weren’t really all that interested and probably didn’t understand a lot of the scientific concepts/terminology I used. I also used to text random facts (usually animal-related) to my phone contacts (usually friends and babysitters) when they did not ask for them. I mean, I wouldn’t go on and on and on when they showed no signs of being interested in what I was talking about, but I would usually send a detailed text before giving up on sharing the info I wanted to.
Nowadays, there are relatively few situations in real life where I feel comfortable info-dumping, really feel like it’s called for. My mom is the person with which I share information relating to my interests the most, since though my biggest interest (zoology/nature) isn’t a major passion of hers, she’s still interested in it. Even then though, I do my best to share relevant information, not deliver more than the dosage initiated by our conversations. I am more comfortable talking about my interests to people on digital platforms. This especially applies to groups of people who share my interests that I meet on platforms like Instagram and Discord. No reason to feel uncomfortable sharing information when you know you’re around people who are equally interested.
