Is she playing hard to get? - 1

I'm your typically 20year old working at this store & whenever I see this woman she's always doing quick glances like looking around. She's tall like me, mascara, long brunette. She seems "fancy", she even drove in a new Honda Sonata Hybrid, soon as she pulled up I could've swore she did a quick glance at me. Maybe I'm imagining things. But whenever she walks in the grocery store it seems like she does quick glances to everyone else also. Also one time she was walking I looked at her & she did a quick smile. A few wks later she came in with some sunglasses, once again being "fancy" I quickly decided to mess with her. I said "you can't wear those" with a smile. She walked a little and smiled at me like "what? Well i'm gonna wear them anyway!" smiling. Some time passed by, I turned around messing with my co worker then she walks pass me looking at me saying "i'm still wearing themm". I look at her trying to think what to say. She starts to walk toward me "why? Why can't I wear them?" tilting her sunglasses down. Then I say "i'm just joking with you" smiling waving my hand, she laughs at the same time with me. Turns around & says "cyaa". A wk later she came in doing quick glances with a little smirk. She did this like twice. My friend caught her and she went around the store real quick. She went to the aisle beside me then changed her mind & came thru my line. I played it cool & she just starts convo & she had to go

Added (1). A wk later I was in the lobby & I could've swore she was staring at me. My friend was in the store and apparently she initiated convo with him like small talk even though they were both in different lines. I had go to outside & i could see her coming my way i made casual glances. She seemed nervous but looked at me & said again "hey hru" with a little smile. I just said "good & you?". Something going on here?

No, you were only playing with her and she was playing back with you, no serious approach that she can play hard to get.

Very romantic! Enjoy your time while it lasts!

She seems friendly. Maybe she was flirting with you with the sunglasses incident. If you want to test her out keep on trying to mess with her. If she follows it and does it too she likes it. If she doesn't return the favor she's not interested. Just become better triends and see where that will go.
