For real real and not for play play

Last night I went to see Love Is A Sniper, by Lola Arias/Compañía Postnuclear.
The piece was very touching and funny and was good to see a piece about love that maintains its sense of humour.

Another touch was made by a post-show comment in the post-show discussion -
about doing something real on stage, like kissing or crying or slapping someone in the face
Ms. Arias mentioned actors who say
"When I kiss on stage, it is not real at all"
But a kiss is a kiss, it is a physical thing,
it is real,
even if the motivation for it is not love or desire.

And if you manage to cry, then you are really crying,
even if the motivation is not the death of your dog but just that you are trying to cry, like it is a skill.

Do you prefer to see something real?
Or do you mind that a performer might not be letting the truth get in the way of a good story?
When you hear a singer sing a song and you know is it biographical - is that cool?
When you see someone crying or sweating or doing something real on stage - is that cool?
Is this cool?
Is that cool?
This guy - cool is he?
Am I cool?
