How to live in peace with parents ?
Not only the great Russian writer Turgenev was interested in the question of " father and sons ", every new generation has clashed face to face over such a problem . The flash of the conflict usually takes place , when the children are teenagers ; to be exact , when they're about 13-16 years old . Worrying about their baby's health , about what school , friends and clothes to choose , the majority of parents are really keen on looking after their kid from childhood on . But when the offspring grows up , they declare , that they wants to be independent . It is so very difficult for parents to understand , that their child has become adult and wants to make decisions him/himself , wants to get freedom , even if only partly . As for me , it infuriates me , to put it mildly , when my mummy comes straight to my room at eleven p.m. and says in a grumpy voice :" it's time to sleep ; honey !", or when she tries to make me put on an extra sweater or a cap , refusing to understand , that I'm able to solve such a problem myself .
Of course , parents wish all the best for their kids , they believe , that watching their children constantly can help avoid making mistakes ( drugs , alcohol , early sex and etc.). Our mothers and fathers are sometimes not successful , when they scold us , for example , as being in infancy . They say :" Shame on you ! You're sixteen and you still don't know what to be in the future , in what institute to pass the exams ,"- and endeavor to make decisions instead of us . Children keep on trying to resist control and enforcement ; they often argue and quarrel with their parents . In some cases the teenagers take extreme measures - they leave their homes , or begin telling lies and doing everything contrary to what their parents say . Well , how to find the compromise , how to have the right for freedom without making parents nervous ? To my mind , it's a mistake to be aggressive and to " fight for liberty "; the right way is to contract with the parents about new concessions day by day , but not without proving , that we , the children , are prudent and responsible . I decided to ask my friends and other people of my age , how they connect with their parents . So , I made a special test , which consisted of five simple questions , and asked my friends and the pupils of one of Moscow's school . The result was really fine .
