Basically, after reversing all of the charges, likes are still likes (and repel) and opposites are still opposites (and attract). The way matter interacts through the weak force has handedness in the sense that you can genuinely tell the difference between left and right. The mirror image of the way neutrons decay is impossible. Parity and charge are how anti-matter is different from matter. The most important, defining characteristic of time is entropy and entropy treats matter and anti-matter in exactly the same way; the future is the future is the future for everything.
