When it comes to emotions, there is usually a process. Sadness. In the first level, they REALIZE. That means they may have an expression that makes them look traumatized. Then, they slowly process. A few tears in the eyes, but not dripping yet, they may be trying really hard to hold them in. Then maybe a big burst, quiet or loud. (In some matters, the process may be quicker or slower, and they be unhappy, but not cry at all.)
