There's this girl I see pretty often at work, and she's always excited when she notices me and gives me all of her attention, standing really close and just being very comfortable. Recently she began to act super weird and I feel like she has no limits set because she always says that she has to see me smile, and when I do crack half a smile she claims that now she can have a good morning, and she feels so comfortable that she even let herself touch my lips because I refused to smile.

Does any of this mean anything? And in general, is it good when a woman feels this comfortable with you? because for me it feels like she doesn't take me seriously.
