I am not alone!

From ' Robinson Crusoe' by Daniel Defoe (1719)

It happened, one day about noon going towards my boat, I was exceedingly surprised, with the print of a man's naked foot on the shore, which was very plain to be seen in the sand. I stood like one thunder-struck, or as if I had seen an apparition; I listened, I looked round me, I could hear nothing, nor see anything; I went up to a rising ground to look farther; I went up the shore and down the shore, but it was all one, I could see no other impression but that one.
