Love... It's hard to imagine world without it. However , now the world is cruel because of the lack of love. Аs mentioned in the song of the famous British band " The Beatles" - All you need is love. I think so too 'cause it is the main ting in your life.
Futhermore, love accompanies us all life. When we are born we are surrounded by affection and care of our relatives. Then, when we grow up, we meet our first love. So we have a family with a nice child and good wife. But not all the people it happens. More of them are cruel and unkind. And i think that's because of not having a love.
ну как-то так, надо что то дополнить
