There are strangers and there are strangers…
Out there there are billions of human beings whom you and I will never encounter. With a few we manage maybe friends on Facebook - these friends are still strangers.
There is another type of stranger which is far more moving; those that we are estranged from, “no longer close or affectionate to someone; alienated”. These people were [and are] part of our lives yet they stand apart, separated.     (2011)
