You knock over some dominos, they all fall one after the other. That is coherence.

You knock over some dominos, somehow, they fall over in a seemingly random order. This is decoherence.

It's when catbox isn't sealed tight enough and leaks information into the environment which turns the reduced density matrix into $\frac12 | live \rangle \langle live | + \frac12 | dead \rangle \langle dead |$ but also $\frac12 \left( \frac1{\sqrt2} | live \rangle + \frac1{\sqrt2} | dead \rangle \right) \left( \frac1{\sqrt2} \langle live | + \frac1{\sqrt2} \langle dead | \right) + \frac12 \left( \frac1{\sqrt2} | live \rangle - \frac1{\sqrt2} | dead \rangle \right) \left( \frac1{\sqrt2} \langle live | - \frac1{\sqrt2} \langle dead | \right)$ .
