Sounds like she is thinking and her conscience may be bothering her a tad. Gentleman sounds okay. My daughters father was a bartender on weekends for extra money when I met him. Others might not agree but with the gentleman being a part time bartender-he more than likely will not want her to drink!!!! I know mine didn't and I did not. He was ungodly protective. I found with my 3 girls-the evil eye did more than a lecture or a good oldfashioned scream match. One slip is not the end of the world. Give her a chance-she is still trying to find herself I think.
Hugs!!!!! Hang in there.
