It took a few weeks, but my daughter finally viewed the situation as I did, and told the girl not to bother her any more. You are smart to not leave them unsupervised. But they can make lots of plans when they are together. Be very cautious and very wise. If your daughter's friend is involved with bad things, especially when it comes to legal issues, then it is only a matter of time before the friend tests your daughter's 'strength in friendship' to back her up in other serious matters.
Friends have a way of influencing others into making the same choices as they are.
I realize that you think of this girl like a daughter, but if you come straight out and say that you are not allowing your daughter to be around her due to her behaviors and bad choices, it may be an eye opener to her. Not only would you be saving your daughter from a troubled path, but you may just set the girl on a straight one as well. It is your job as her mother to make sure she is making the right choices in life. Once she becomes an adult she can do this on her own. All rights reserved.
