That's it ,some children just do not want to go down the same road. It can also be the habits, I know parents whose children will sip out of their parents glasses. That worries me. They are only around ten years of age.
If an astrologer can see in the chart that their is a higher chance of addictive habits, then in my mind it must also be a karmic thing. Like you formed bad habits in a past life, isn't it then likely to continue in this one, until self does something about it. Free will is here to make choices.You know "Beat it"
