Demonstrative over

Ignoring. You could argue she's got Creative Fe and is an SEI, however she seems to value

When it comes to the expression of emotionality, I find

From most to least outwardly expressive* (ime): ExFj > ExFp > IxFp > ExTp > ExTj > IxFj > IxTj > IxTp.

The louder, brighter, more varied and intense any of those elements, the more "outwardly expressive" the person.
The more monotone the voice and sporadic or weak the facial expressions, the less "outwardly expressive" the person.
