Does she tilt her head when she speaks to you or you speak to her? Does she look at you even when you're not looking at her? Does the pitch of her voice ever change while talking with you? Like, get higher or softer than it usually is? Does she seem nervous or fumble her words? Play with her hair? Caress her own arms or anything else while around you? Touch her neck excessively? Ask you questions about yourself, your well being, or your interests?

These are all signs that she likes you.
