(Topic) Do your family and friends know you are into trains?

I am the same way, I don't talk about it because I don't think people (including family and friends) can understand it. But when I do meet someone who enjoys trains and even collects them, I light up. It's pretty awesome to meet others who are into trains.

But the same can be said of my passion for Japanese culture, diecast metal cars, baseball and VR (Virtual Reality), I can't talk about that with family or friends as they are not into it as much as I am.
