Search Results: showing him i''m interested

There is a girl I like in my church and I can't really tell if she likes me or not. I have stared at her a little and she has noticed it. She's been catching me staring at her and now she looks if I stare at her. She's been trying to see if I look at her and I now catch her with an eye. Sometimes she smiles most the time not. When I quickly glance to see if she looks and when she does, she kinda keeps looking for a second but I can't really tell because I look away quickly. Now most the time when she's with her friends she doesn't really look at me. Anyway she's done some of what I think is flirting, like once her friend teased me a little and she suddenly joined in and said "yah (my name)" and mocked what she said. Then I was playing piano once and she walked by and walked into the room and put her arms around the piano and listened to me play. There's also been some "chance encounters", where she says something to me that is friendly or something. Like i don't know, once there was a weird noise in the gym and right when I was about to walk in she walked by with a friend and she said "Are they surviving in there?" and I said something that made them laugh hard. Then another time she was looking for her brother and I told her he went that way to look for her where she was going and she said "oh", then looked at me real quick smiled a little and said "Im gonna scare him!" So anyway those types of opportunities we get to talk a little. I still don't know, so is she possibly interested in me?
