Things we bother(ed) about
Ask your mom what were the things she bothered about as she was a teenager. Or you can ask your father the same question. It is common and clear that their answers will strike you greatly. You will realize that there is nothing in common between thing your parents were bothering about and things you are bothering about. You are people of different generation and not only generations.
Time never stops and so development never stops, thing are changing constantly and every new generation has something the previous generation was deprived of. So, they were bothered about something they recognized as well-fare and we recognize as the most common thing in our life. But why talking about material stuff, let's talk about things that bothered their minds.
There were not much of those things. But all of those things were about something very precious and valuable for them. It was things they were thirsty for and those things were love, happiness and so on and so forth. The previous generation bothered about peace in the world, about people who suffered for nothing and about ways to help those people.
But the modern generation cares only about their precious selves. It is the selfish policy suggested to children nowadays. For some reasons they are taught to be selfish and care only about their selves. They are taught to be cruel and deprived of compassion. If there is someone who is weaker they will never give him a hand, though they will do their best to make him weaker than he was.
