Same, I feel so bad for people whose spouses aren't interested. I hope they're exaggerating here, because the story is sad.
My story, I'm a giant train nerd. Any types, got model trains, ride them frequently, it's my thing. For the first few years I was terrified to mention it, and man do I regret not doing it earlier. She is interested because I'm interested! She now shares my interests with me. We've gone on now 6 or so long distance sleepers here in the states and love it. I can't imagine having a spouse who actively didn't want to share interests
