Tipping is a sensitive subject for me . <| sep |> Another thing to think about is that NFL kickers often start as soccer players , and the popularity of soccer among black Americans is pretty much nonexistant . <| sep |> I ' ve heard complaints about the complex plot , but not about handholding . What do you mean exactly by that ? <| sep |> Do you have reading comprehension issues , that you have to spell out everything ? You missed the essence of my comment where I stated that you basically recycle the petrol , using it once as a packaging in the form of plastic , then you burn it it ' s recycled as it gets recirculated in the industrial process . It ' s not possible to recycle it ad infinitum like iron , but doing it once is a step forward . Do you want me to spell that out for you ? Recycling is a broader notion , check out wiki as well
