First I saw a clip about a man taking a concubine—I didn’t know what to say, given my own situation. Then I came across a video about “separation of issues.” The speaker said living should be like being a pig: a pig spends every day eating, drinking, and sleeping, but we don’t notice how much pain it actually endures. The whole message was about letting things take their natural course. But I didn’t quite get it—to me, it’s about doing everything in one’s power and then accepting fate.In my view, “doing everything in one’s power” means exhausting every possible action, even those you’ve only heard of. And “accepting fate” means having self-awareness, understanding the world, and making a broad judgment of how things are developing. That’s what fate is.So what should I do? With that in mind, let me first take a look at where I stand. Where to begin? Maybe with the tripe incident. It’s not a long story—I just wanted to eat tripe and asked to buy a bit more, but my ex-husband said no, claiming we wouldn’t finish it. That suddenly made me feel deeply sad.

Well, I suppose it was all about arguing to defend my interests, my sense of self, my dignity. Of course, I’ve read many books. The irony is, my introduction came fromThick Face, Black HeartandHow to Win Friends and Influence People—and I have to admit, I got pretty good at applying those.Anyway, after I started learning C, I found it made me even better at arguing. For example, you can’t call a function you haven’t declared. Or how about the call stack—last in, first out? Wait, did I get that wrong? Someone fix it.Or think of it like this: Mom takes care of Shushu (my daughter), Dad goes to work. Mom is a constant within a constant; Dad is a constant with predictable variation. From Monday to Friday, he works; weekends he rests. But honestly, Dad is also great with Shushu.Then I accidentally
