There's a particular career that interests me which I'll likely never be able to do. So when I stumbled upon some videos on YT of a person in this career doing his thing despite the difficulty of juggling a camera while doing it, I was intrigued. I commented thanking him for uploading, and he replied "You're welcome. If there's any other procedures you'd like to see, just let me know and I'll make a video."
This strikes me as really, really sweet, not only because he's offering to go through the effort to make more videos upon my request, but because he's graciously assuming that I know enough about the field to know what to ask for, rather than acting all superior.
I guess I could just be really hormonal, or maybe I don't get out enough, but it made my day. This guy also volunteers as a bush firefighter.
ETA: No, I did not reply to his reply with "Wow, someone on YT isn't a troll!" Although I thought it.
