Don ' t know if this helps , but I sometimes smoke to help . <| sep |> That website has given me cancer . <| sep |> There was a really big lock on the garden shed . And John only gave away the key like twice a week . <| sep |> I don ' t think you really understood the film . It ' s not about how important communication is , it ' s about how important it is to understand communication . The aliens say , use weapon when they don ' t even know what Weapon means . So instead of jumping to conclusions the term you meant to use Ian and Louise know that they mean something else . But the movie isn ' t about that . It ' s about understanding how important proper communication is when it comes to society and civilization . And how important it is for us to unite together . The film gives us hope by letting us know that it is possible to unite together as a world and strive towards a better future , and that we don ' t have to keep going down this current path .
