If I understand correctly ...
any adult can give another adult his MB to use in the FP line (even if it's a man using a woman's MB),
and any kid can give another kid his MB to use in the FP line (even if it's a girl using a boy'd MB),
but an adult can't give a kid his MB to use in the FP line, and vice versa?
Or is that possible too?
