I am actually really curious, in what ways is it rewarding outside of loving anyone else?
However, there is also a bit of an effect where someone you care about is not particularly thoughtful, so when they do go out of their way to be kind or help you out, it feels especially good and shows that they really do care about you. If that makes sense..
I can't say I personally get it, but I respect you and your family for their empathy and compassion.
