A Terrapin's Visit

I woke up one morning and walked down to the gate to get the newspaper. But I didn't walk back into my home with the newspaper alone - in my other hand I held this medium-sized terrapin.

Where did it come from, why it came here, and how!?! I had no idea. There was a possibility that it crawled all the way from the river, but why would it do that? And I have no idea why he chose our house to visit. Anyway, I took a few shots of him and kept him for the day. He was a shy guest as he hesitated to show himself when we went over to 'serve' him.

Here's a close-up shot as he retreats into his carapace.

That evening, I left to the river with him along and released him. He jumped in as soon as he sensed water.
