Explications:
today in our generation alot of people are demanding to remove historic monuments claiming that they are useless and pathetic and that no one need them , thinking that they can use that empty place to build something big and important instead of an old building but the only problem is that they forgot that other people's great moments happend there and that this monument is a part of his memory his feelings and his happiness in his childhood or now plus, that monument could be an important tourist attractions source that help the economic part in your society to grow up so that's how a useless building could be a way to find the hapiness for some people and a unique memory for some others and that's how the government should respond
