Odds are, if G-Forbid this ever happened, we would be by her side every day, telling ourselves it is the right thing. It's the least we could do after all she has done and continues to do for us....
But it makes me wonder... What would your mother prefer? What would have made her happier? What choice would she have made for you if it was up to her?
Human nature is an interesting thing. Always presenting conflict every step of the way. The right thing can and will almost always be a representation of what your heart desires.
The weird part is, the more important the decision, the easier it usually is and the choice is more obvious.
The hard decisions usually are not that important, but rather a scenario with both options are legitimately justifiable, and both choices can be justified or vilified.
