Oh, Kate, what you have done for your children is grand, they are enjoying life in all its ups and downs, but that is a gift Mother or parent can give, gift of life, love, and friendship. As I often say the only thing we truly posses is our ability to share in love, thats all, we don't even posses love it self, it is like a gentle wind caressing, swaying trees in a dance, but invisible otherwise untrappable, however powerful beyond belief. Your love lives in them, and that is a gift to know! So if you must do shed the tear, but know of what you have done did not happen in vain.
All my love, Inna.
