I have a different take on this. Perhaps it's my age or maybe it's because I think young people should be told the truth with no apologies when the truth is: Dad and Mom tried their best.
This is life...we can try out best...give it our best shot..and then find we have failed in some way. Our kids should learn that lesson and learn also that to try our best and fail is not a reason to apologize it is a reason to learn that life is not a game where we can always predict the outcome and come out smelling like roses. No, life is a struggle but a struggle well worth it if we are trying our best, giving it our all. If we have done that there is no reason to apologize for choices we had to make or chose to make.
There are thousands of choices good parents make and good loving parents may in hindsight wish they had made better choices, different choices, for their children. That though does not mean a parent should apologize for a choice made in good faith, with good intentions and with love. Should a father in the military whose family has had to move many times or a mother who chose a dangerous job in a foreign country because it paid for her child's education and then was seriously injured, should they apologize also? If they were good, loving and responsible parents why should they apologize for a choice sincerely made?
It is a lesson learned for the child- Son, we all make choices and at times those choices may later prove to be less than ideal or even wrong but this is life. I have made my choices with the best intentions, you someday will make choices you may later feel were best not made. But if you did your best what more can be asked of you?
All one can do is learn and move on. To wallow in our sincerely made bad choices is a waste of breath and time. Move forward son and hope that when your turn to raise children comes along you will not overly beat yourself for the sincerely made bad choices you yourself will almost positively make.-
It is one thing to apologize because our hearts impel us to but another to apologize because we feel we owe it to our children. What we owe our children is love and the best choices we can make with the information we have available to us at the time. What more can we do?
