The Importance of Alcohol in the Life of an Elder Sister

i had two elder sisters and i have an elder brother and um at my brother was six years older than me. He started getting in trouble at probably he started running away from home when he was about 11 or 12 years old. So but my elder sisters don't have a problem and i have one sister that you know has drank and done other things her whole life. She's not an alcoholic but she gives a good impression of one, she says.
