So exactly what is your point?
I see you saying that nobody except a metzuyan should learn for 10 years. That I don’t agree with.
I also see you saying that only a metzuyan should ask for support for the years he wants to learn. That I also don’t agree with.
I also see you saying that parents should know their children. That I agree with, but still don’t agree with the application here.
I also see you saying that support should be shared between the parents if they are able. That part is worth discussing.
