You know, the kind of thing that most other people might say is just okay at best, but you think is absolutely splendid. Something that others might find insignificant, but you find deeply relevant.
Anything goes. It can be a food, a movie, a breed of cat, a programming language, or that one guy who always waves to you on your way to work in the morning. It doesn’t have to be noteworthy to anyone but you.
Also, don’t just name what it is, but also share your fondness. Show us why you love it so. Convince us to see the same merit in it that you do!
