Answer:
Dear mom,
I know that this is coming late.
I do not know how else to say this Mom but I am so sorry. I am not saying this because I feel bad that I was absolutely wrong, and you were right; I am saying it because even if I really didn’t want your advice, I could have at least done so without offending you or ignoring you.
I realize there is more wisdom in the advice you give me than I know, do forgive me.
I cannot even begin to imagine the hurt you must feel watching me do the very things you warned me of and falling victim to the very scenario you tried to prevent me from.
I love you now, forever and always.
Thank you.
