Does this girl like me?

I was at this house party talking to my roommate in the dorway of the house and this girl and her friends were trying to get through. "She says "Hi (I said hi) I saw you at Palmer (another house party) earlier and I wanted to say hi but I was too shy." She kind of had a smile. Her and I talked for a couple minutes and she went to get another beer with her roommate. As she walked through to go back outside, she grabbed my hand and held it and asked "Whats my name?" I answered and she just looked at me and smiled and continued to hold my hand as she walked away. Do you think she likes me or is she just looking for attention?
