People think that some of the reasons children run away is because their parents fight with each other and they sometimes take it out on their children. For example, their are kids that their parents fight and they end up getting a divorce and they have to choose to stay with one of them. In some causes their parents, when they fight with each other they probably drink. Therefore, when they're drunk or something they come home and if they get bad news about that their child didn't behave in school or that they got in trouble. As a result they would probably use violence because their drunk or sometimes they just take it out on their children. Consequently, that's why children run away form their house.
The main reason why children run away is because they don't get along with their parents. Children by the age get an attitude with their parents and think that everything is right when sometimes it's not. When children have to help out around the house and they don't want to do it so their parents remind them and they get in an argument with them because they don't want to help so than they get grounded, they make a big deal about it. Another thing, is if they got in trouble and thier parents wanted to talk to them and they did but they ended up yelling at each other and kids can't take it so they just leave their house and sometimes they came back or sometimes they don't.
In conclusion, that's why some people argue about children running away from their house because of many reasons. For these reasons that's why you hear on the news about parents trying to find them and they might come back or they might never see them again.
