Please help me!!

  My husband and I had a problem about our holiday last year. I wanted to have a lazy seaside holiday because I was tired and needed to relax. I loved lying in the sun, drinking iced beer and reading a good book. But Robert liked  busy cultural holidays. He liked visiting art galleries. He hated sunbathing because he always went red, not brown. The travel agent tried to help us and suggested Greece. I said I love to sail to a quiet island, but of course Robert said he’d like to stay in Athens. It was easy to decide what to do,  we flew to Athens together, Robert stayed there and I traveled to the island of Kos!

Facebook is a great app that has the highest members in the world.On Facebook,you can share pictures,videos,...Not only that,people can also chat,make friends or even sell and buy things.That the goodsides.Not only good effects,there are many bad effects if we addict to it.Firstly,to ourself, sitting infront of the screen for too long may hurts our eyes,body and minds. It will make us tired and lack of energy.This will make our grades get low in an instant.Secondly,if you do any unpleasant things, some people may take pictuers or videos of those not so nice moments and sent them on the app.People of all around the world will see them, then disgusted you and you will be make fun by mean kids and may seperate the world.Also,if you make friends on Facebook,there may be some bad people that you don't know.They may hack into your account to do bad things,boast your unpleasant things and may even lie to you to get money.So,in my opinion,using Facebook is good.But,you shouldn't addict to it because it may harm yourself,your family and your friends.
