I disagree with the author when she/he said that our parents are the ones who shape our personalities and everything else. However, I feel that not only parents do this, others too, which is friends, parents and of course, yourself.
½ of the day you see your friends at school, eat with them, work with them and everything else. Some people even spend more time with their friends rather than their parents. Therefore, people tend to feel closer to their friends instead and listen to them more, follow what they do. Good influence friends help you, guide you while you grow. They make you feel welcome and do not want anything from you in return. They make you a better person in the present and the future. However, this world does not only have good people. Bad influence friends can bring you to do things that you do not want to do, due to peer pressure, example, smoking, drinking alcoholic drinks, etc. People our age usually give in to the peer pressure due to fear of losing their “friends”. They want to fit-in, and rather do the bad things and be famous with lots of friends, rather than being alone. Therefore, friends can shape how you grow as a person. They partially determine whether you go to the right path or head down the wrong path.
Parents are our guides since the day we were born. They fed us, sent us to school, paid for all our needs. Maybe our personalities when we were young was shaped by our parents. However, at this point of our lives, being a teenager, it is not fully our parents shaping us anymore. Parents are our role model. They have taught us what is right and what is wrong, and this has helped us until we grow old. Parents have done everything they could to make their child be a good person. Parents teach us everything they can, hoping we will follow them. Parents are the ones who have taught us to have moral values. Therefore, parents also partially shape you and your behaviour.
Your parents can guide you and help you in everything, your friends can influence you in a good or bad way, however, it is all up to you whether you listen to them. Your friends can ask you to smoke or take drugs, yes, it is partially their fault, however, it is your choice whether you would take that cigar or drug. It is you to determine your future. It is you to decide whether what you are doing is right or wrong. Your parents can scold you for taking the cigar or the drug, however, it is still up to you whether you would change, or just take another wrong step. You shape your own behaviour, you shape your own personality. At the end of the day, it is still up to you whether you want to do this or that. The choice is always yours.
