I'm probably being interfering but... I am friends on Facebook with a girl I used to babysit for about 10 years ago. She's now 17. Seen a photo on her Facebook (from months ago) of her smoking which makes me very sad... part of me wants to ask her about it and tell her it makes me very sad to see this. We've always had a really good relationship and she regards me as a friend / big sister and I would hope she might think twice about continuing if I say something. However also it'd probably sound way too judgemental esp. to a teenager wouldn't it! It is only one photo, I am probably over reacting. I just think of me and my friends at that age and all the ones who still haven't managed to quit and would have been horrified then to know they'd still be smoking now. It makes me sad to see this little girl I used to care for smoking.
