hippies in the 1960s and 1970s a hippy was a person who opposed the normal standards of society. hippies wore unusual clothes. girls, for example, often wore indian-style silk dresses and both men and women usually had long hair. they lived in groups together,often in places in the countryside. hippies believed in peace. a lot of hippies in the us and europe went on marches to protest against the vietnam war. when the hippy movement started in the us, especially in california, young people showed their peaceful feelings by wearing flowers in their hair. for this reason, they were also called flower people of flower children. hippies listened to rock music. they enjoyed the songs of bob dylan and it was at this time that the beatles wrote songs like `give peace a chance` and `all you need is love`.

advertisement plays a big role in our lives. some people don't like to see it everywhere and some people don't care about it. as for me, i think that  advertisement is an inportant part of our world. to keep the economy up we have to sell goods to people but it would be inpossible to sell a lot of products without advertising it. but i believe that it should be limited. i can't stand when i am in museum or theatre or any other cultural place and there i see commercial everywhere around me. i also don't like when i watch an interesting movie and it is interrupteb by a commercial. so my opinion is that the advertisement should have a right to exist but it should be limited.
