The Stare

I think my turtle is really scared of me. I've been observing from a not too close distance but today I tried observing more closely to its tank; right away it tucked its head into its shell. I got on my knees so I could be at eye level and I could see my turtle's eyes just staring at me. It still remained with its head tucked in. I'm not sure who was more intimidated between us, it made me shiver and uncomfortable. 

I wonder why the sense of awkwardness was felt between my turtle and I. Did my turtle feel the same thing as I did? It wasn't fear I felt for there was glass separating us. It just didn't feel right.
