You found Sara boring and whiny, Steph? Oooh! I fully sympathized with her being sickened to the soul by all the tragedy she had to deal with on CSI. I was glad she had the good sense to walk away in time.
Not everyone has the ability to step back and emotionally shut out the horrors. That is why we so often perceive police officers, or nurses, as hard and cold. They have had to distance themselves from what is happening in order to be able to deal with it.
Lady Heather had her own form of wisdom, but she also had a depth of cynicism that I don't believe was true of Grissom. He was detached and realistic, but the one he loved, and chose, was the caring Sara.
