I'm writing to ask for some advice concerning my problems. First of all, I do not know what to do to stop my parents from making me eat meat. I've decided that I want be be a vegetarian and told my parents about it but they do not want to accept my decision. They still insist on my eating meat and we often have quarrels over dinner. They say I'll have health problems but I do my best to provide my organism with all the microelements and vitamins-I eat a lot of fruit and vegetables. Can you suggest any solution to the situation?
I have also another problem. My younger sister comes to my room whenever she wants to, without knocking on the door and without being allowed to enter. She also borrows my clothes without asking me for permission. If I try to complain about it to our parents, she always starts quarrels and says that I lie. What can I do to improve my relationship with my sister and with my parents?
