A sad side of older child adoption

One of our adult daughters has decided our usefulness to her is done and so she will be moving back with her biological parents next week (the same biological parents who threw her out less than three months ago when she called us tearfully asking to please send her a next day airline ticket which we did).  Because she does not want to have to work for her needs and wants but rather wants a hand out she plans to now live her life in a brawling, immoral household, not caring who she harms or hurts in the process.  As older child adoptive parents we must realize that we help children because it is what God has asked us to do, not because we are expecting love or gratitude in return because in most cases this will not happen.  We are serving others out of our love and servitude to God...
