A trust-in the sense of a valuable asset placed in the care of someone to whom it does not ultimately belong-captures, more or less, my understanding of what it is to have a child.

I thought, how would I feel if my son gave one of those [underprivileged] kids chicken pox? For him it's not a terrible thing. We have good insurance and easy access to health care. It's a different situation for another family. I didn't want to make the decision for them.
