Well, I’m going to take a chance to disagree with PBA (please don’t take my head off) and say that I think you just taught that it’s OK to quit. Sometimes Hashem puts us in situations that we cannot change and we have to learn to deal with them, even if we’re unhappy about it.
I’m going to bite your head off.
Firstly, I don’t know the first or last thing about this particular circumstance. So I can’t possibly know if it was really the best thing for the daughter. I was glad that the mother made a decision that was hard, with her daughters best interest in mind.
Secondly, (here comes head biting), sometimes Hashem puts us in hard circumstances which we can change. Like this one. I don’t see why you need to do hard things which you can change just to prepare for the ones you can’t. There are enough hard things which we actually cannot change, to provide all the training required.
