~ я не тот человек , который любит что-то говорить и объяснять — а тот человек , который любит что-нибудь послушать и за кем-нибудь понаблюдать.
Not everyone will love you and take care of you as much as you. No matter how much you have done and how much time you spent on a person, some people simply do not see the problem of not giving anything in return.
You will meet people who behave selfishly and manipulate without caring about your feelings. And this is normal. That is life.
