To avoid being caught in a situation involving alcohol, say no to large parties that will not have any parents in the house. Another tell-tale sign is when people are secretive about inviting people over so as not to get "ratted out". To refuse alcohol, I would first state that I'm not into drinking in a cool and composed manner so no one will believe I'm planning on reporting them. Then, if they keep persisting, I would tell a white lie that addiction runs in my family and that a family member passed away from drinking, and that I wouldn't want that. If they still persist, I would leave the party or wherever alcohol is present. I hope I helped!
