Is it really true?

Movine: No Reservations
Casting: Catherine Zeta-Jones as a perfectionist chef Kate and Aaron Eckhart as Nick - an opera loving fun sous-chef. Add to it Zoe (Abigail Breslin), young niece of Kate who's just lost her mother..
Its a lovely movie, hilarious and touching... Along the way I came across a quote that got me thinking... Its Kate talking to Nick when Nick is offered a job by Kate's boss without consulting her and she is feeling seriously threatened:

Kate motions at the kitchen that she has worked so hard (and where she loves to be) and says to Nick,
"This place is my Life! This is who I am.."
And Nick says,
"No. It is just a small part of who you are.."

I disagree, Nick.
