Choosing the wrong friends can lead to a range of problems. To begin with, if your buddies insult others or you, you may become accustomed to being treated badly and direct this energy onto your family. Bad friends may put pressure on you to do things you don't want to do, which could result in negative results. Friends who do not care about your well-being are unlikely to assist you, so you may distance yourself from your family, fearing that they share your sentiments and are uninterested in your well-being. Friends can be disrespectful about your family at times, and this can make you feel obligated to agree with them, which can lead to them being rude to their own family members.
