Do you have a friend who is upset about his or her parent’s drinking? You want to do something to help, but what? Your friend may not talk about this with you, but you can still be a good friend. One out of four children lives with at least one adult who has alcoholism, so your friend is not alone.

●Be a good listener. Your friend may need someone to talk to. Listen to your friend and suggest that she or he talk to a trusted adult in addition to talking to you .You can offer a good listening ear, but sometimes an adult is needed for more serious things. Maybe you can suggest a caring adult for your friend to talk to, such as a teacher, a neighbor, or a grandparent. He will listen and support your friend, and he will not hurt your friend or put your friend down.

●Don’t spread gossip(闲话) about your friend’s family. It’s okay to tell your parents or another trusted adult what is going on, but respect your friend’s right by not telling other kids in your class.

●Ask your parents if your friend ___________your house, and then invite your friend over for enjoyable activities or to do homework together. Sometimes your friend might just need to get away and have fun being a kid.

●Don’t ride in a car when a friend’s parent has been drinking if you can avoid it. It is not safe. Call your parents, walk, or try to get a ride with an adult you know who has not been drinking. If you must get in the car with a drinking driver, sit in the middle of the back seat with your seat belt fastened. Lock your doors and try to stay calm.
