“Tell us how you feel. That’s the only interesting content.” — Heather Urquhart, 5th November 2015, Barcelona (ES)
This was said during a long form musical workshop. It’s true in the context of singing (sing about how you feel), but by extension it counts for all dialogues in all scenes, doesn’t it?
Expressing how you feel is a great fallback when in doubt too, since it will certainly be a sentence that lives in the now.
Of course, don’t make up a feeling. Always tell the truth on stage.
