Did I overread this?

There's this female coworker i have. I found out through another coworker that she asked him for my name and age. I say hi to her rarely. Another time i was returning back to the store and I saw that the lines at the cash registers that people were blocking down the middle so i tried going around the cashier and it was her and she turned her whole body around and stared into each other's eyes and I think her pupils dialated. I notice sometimes that she takes her break at the same time I do but that could be a coincidence. She sits at the table next to my table every time. We use work phones to communicate. There were 3 people in my department who had work phone and the work phone tells you the names of the people in the call. Mine and hers only showed up. And she would ask if I'm busy first everytime before she told me what she needed. She doesn't usually do this. She usually tells other people what she needs. When i walk past her i usually look the other way or down at my feet because I won't have any confidence and the other i decided to look at her and i think she was looking but she turned away and i saw her smiling. Did i overread this?
