As You Like It
This morning I finally made coffee for my wife after a long time1, using my brand new kettle for a drip brew. A technique that any purist would probably shudder at, but no purist were in the room when I made it so I'm ignoring that2. As I brought it to her in bed, she asked me if I put in sugar; I answered that I didn't and I'd do it right away, but that maybe first she'd like to taste it without. As I anticipated, it was "not as bitter" and, while a bit of sugar would've been more to her taste, she preferred to take it without this time.
I see it as a kind of problem-solving: what can it be done to make something that you like a certain way to still be enjoyable in a different one, making you discover another side of it, or maybe just appreciating more your specific preference? It's different from pushing "the right way" or "just another one" because there's understanding behind. It's "have you tried this different way? It has X instead of Y, serving the same purpose, what difference do you notice?".
I really like doing it myself3, and I love when the other part is responsive. I don't like when they see it as an attack or me trying to "fix" them: I don't think there's anything to fix if you don't like coffee, but maybe you might enjoy a very specific way to drink it. Maybe it could be a way to share it with someone else, even though your ways are pretty different, or you could teach them your way.
Or maybe you could just not give a fuck and go on with your life. You don't have to like coffee, you don't have to like roguelike deckbuilders, and your preferences won't attack those of others or the time you spend together, unless you're forcing yourself to do that very thing just to hang out. And even then, there are no absolutes.
I guess my absolute favourite is coming up with something that another person didn't know they liked: figuring out the criteria and producing a picture that fits perfectly. It's probably the part I like the most about my work.
