A hen in my office....

Symbiosis is a term that my biology teacher used to insist on my head not knowing that i will experience it, It simply means the relationship between different living things that depend on each other, Its surprising that a particular stray black hen walks into my office( community knowledge center) every day at around 10am not to obtain information but to drop an egg.

I do provide the hen with a comfortable place just above my library shelves,to lay the eggs and I in turn obtain eggs to accompany my sandwich in the morning is that a wonderful symbiosis? may that hen live forever........
