The other thing she likes to do now is if she is saying something serious and wants me to focus on her, she will put her hand on my upper arm or shoulder and look me in the eyes.

This started about a month ago, but now she seems to do it at least once each time I see her (and she holds that contact longer each time to). She's only the second girl I've had this comfortable with me. I just want to enjoy every moment of it.
