There are no strangers. One hundred and seventy-five thousand (175,000) years ago our ancestors, all 600 breeding pairs of them, hung on precariously to the shores of South Africa.
Today all those you see in the world, in your towns, cities, on-line and in line are their descendants and therefore your family. Treat them as such.
To put it another way:
If you see, hear, smell, taste, touch (can be a metaphor) anything that you resonate with - reach out and he/she/it may reach back at you...
Bottom line: Love Is The Answer.
