Why did my crush say hi then look away?

The last time I saw her, I was at her house. When I first walked in, she was watching TV. I said "hello" to her and a second or two later she looked over at me and said "hi" back. Before I could say anything else, she was back to watching TV again.

Could it mean she likes me and is just shy? After all, she does other things such as looking at me when I'm not looking at her, mimicking me, asks people she knows questions about me, shows concern for me if she thinks I'm in trouble, her friends act differently around me, blushing around me, etc.
