But what makes one child a target and another not? Huggins (2016) seems to have an explanation. He made a list of what can put a target on a child's back. Being different is the number one reason. Being different can range from a person's weight to the outfit they chose to wear that day or the hairstyle they sported. Another cause of bullying may be not having many friends. Without an abundance of friends, one may assume that there is something wrong with this person and therefore make them an easy target. If someone really has something wrong with them, such as a mental or physical disability, this can increase the risk of being teased even more, especially if they appear weak (Huggins, 2016). On the other hand, if a child has the same advantages and disadvantages as the bully, he or she probably won't be bullied. The expression “Pick someone your own size” comes to mind. Bullies like to target someone they perceive to be beneath them or to be smaller themselves, because it's easier and, for them, more satisfying. Due to all the listed reasons, children may develop problems in their own lives. Often, a targeted child may develop concentration problems and have difficulty learning in school (Jan and Husain, 2015). This makes sense because they will likely spend the entire day worrying about what will happen next instead of focusing on their schoolwork. Although decreased concentration is one of the most common effects of bullying, more serious problems can arise. A person who is bullied may be more likely to miss school, which will greatly harm their academic performance. It can also lead to depression and more serious suicidal thoughts or actions (Rao & Simkiss, 2008). It can be easy to focus only on bullies and bullied children, but it affects more people than children.
