"A bone to the dog is not charity. ... Charity is the bone shared with the dog, when you are just as hungry as the dog." -- Jack London

Jack London was not an authority on the matter.

Spoken like someone who hasn't read much Jack London and knows nothing of his life.

Assuming that someone who has read much Jack London and knows about his life would come to the same conclusions as you regarding his expertise on the matter is an easy trap to fall into.

Two philosophers were crossing a bridge over a koi pond. One pointed to two fish swimming in the pond and remarked: "Boy, those are some happy fish." The other replied: "You, not being a fish, don't know whether they are happy or not." The first said: "You, not being me, don't know whether I know they are happy or not."

In case it’s not obvious and extending a generous interpretation to your comment - i did not imply she is giving as sacrifice.

I implied that the limits of her giving are not informed by any kind of sacrifice.

In contrast to me, you, and 99.9% of people giving to charity and having a limit based on sacrifice.
