The following is a letter written by Elder Paisios the Athonite to the nuns of the Monastery of St. John the Theologian in Souroti sent in the Spring of 1975. At the time he lived in the Kalyva of the Holy Cross.
In your last letter you sent me an icon of Adam and the animals in Paradise. So I thought I would send in my turn the drawing of a bird, my closest friend, because if I sent you the drawing of a snake, I think you would be captured by fright. I have named him Olet, which in Arabic means "child". He lives in a hill five hundred meters from my kalyva. Every afternoon I bring him goodies and treats. As soon as I give him something to eat, he takes a little and leaves. I call for him to come, but he leaves and after a little while he comes secretly from behind and hides under my jacket. When I go to leave he walks behind me at a distance of about one hundred meters and I, so that he will not continue coming behind me and get tired, leave him a crumb so that he may occupy himself, and I leave quickly so he will lose me.
