That's why you shouldn't help others.

We went to a girls' night out once. I didn't know one of my friends has a drinking problem. I didn't drink because I was supposed to drive. If I had to do it again, I would've just taken her cell phone away from her. She made phone calls to everyone on her cell phone telling them she was drunk... She told me she loved me couple of times and asked if I love her too. Crazy night... And then she got herself in a big trouble with her mother and brother over this. The best way to handle this is to let them call themselves after they are sober.
