Explanation: O sentido é mais de proximidade. De acordo com o dicionário de American Idioms, doorstep significa: Very close; very near where you live or work. Ex. - Mr. Green can get to work in only a few minutes because the subway is at his doorstep. Johnny is very lucky because there's a swimming pool right at his doorstep.
