The reference is weak.
The prodical son, apparently, took his share of teh family fortune and set out one his own. He quickly spend his loot and while starving, realised that his father's servants were better off than he was.
He retuened to his father, prepared to ask to be made a servent. But his father welcomed him with open arms, killed the fatted calf and took him back into the household. Much to the resentment of his brothers.
For this to apply to Jerica, her mother would need to predict her ultimate downfall and say that, when that happens, she will be welcomed back with open arms. To say, at this point, that she doesn't even see herself as prodical doesn't really make a lot of sense. Since, atthis stage, she hardly would.
However, I will make two more points if I may.
Firstly, I had not commented on this before simply because it is not my place to criticise someone's parents to them. Especially on moral matters. That is and must be a matter for Jerica to deal with. They are her parents, She knows them. She knows herself. We can only pray that she has the strength to do what is best for her.
Secondly, this is a reference made by many parents to their children. It is a sad reality that we, as children, need to live our own lives and this will usually not be what our parents have in mind. Those her, who are parents of pre-pubescent children, if they are honest, will admit that they have certain hopes, dreams and expectations of their kids. I am fairly certain most here will try to be tolerant of decisions their kids take. But many of us did have conflicts, ore greater or lesser degrees, with our parents. That does not mean we are prodical.
