When the sea bit my ankles

There was one time I had a misshap at sea and that incident is what I would call as when the sea bit my ankles. This is what happened. I was out at sea rowing my inflatable dingy. I got far out at sea. I was shocked to see the coastline looking curved. I saw with my own eyes, what Pythagoras’ theory meant. The earth is round. I felt a strange pull out, towards farther out into the ocean of water. I was afraid that I couldn’t row back to shore. The current was also pulling me away. I panicked and started rowing. I didn’t stop until I reached the shore. I was so relieved. This was one of the times I felt that the sea bit my ankles and frightened me.

Prompt: The sea bit my ankles.
