A Parent Wonders

A parent wonders when their child grows up......

What one thing will I wish I had done differently?
Will they still think I was a good parent when they're grown?
Will I be happy with what I did for them vs what I didnt do?
Did the things that mattered at the time really matter in the end?
What should I have said?
What should I have done?
Would my parents have approved?
Would it make a huge difference?
Did it really matter?
What was the cost, in the long run?
