Nobody, age does not always mean life experience. I had more life experience at 16 than many adults just because of what life threw my way. Also, growing up the last 15 years or so is VERY different from what it was when our parents were growing up. When I was in high school (almost 15 years ago!!!) I told my mother about what was going on with drugs and all sorts of other things. She was shocked at many of the things going on and she went to PUBLIC SCHOOL IN THE 1960s. Life is different nowadays and parents don’t have all the answers.
What AS said “You WANT what’s best for me… that doesn’t necessarily mean you KNOW what’s best…” I think is a very true statement. Parents generally want the best for their kids and assume they know what it is.
Many parents think they know better; some do. Ultimately, if you are old enough to get married, you are old enough to choose who to marry. For better or worse – no one is living in your marriage but you.
