There's this girl I've liked for quite some time, but I'm not sure if she likes me back. Also, she treats me differently than others. She is playful and touching with other guys, but when it come to me she seems to be avoiding me. She does laugh when I do something funny or stupid and she is always friendly with me. She also complimented me on my handwriting and kindness once. What are some other signs which indicate her interest in me?
