Girls, Why does she smile to herself sometimes?

Anonymous
a girl works in a superstore which I visit often because I live around the corner because I study at university. Once me and a friend was browsing some male perfumes. She asked if she could help. I said yes which is your favourite. She picked one and my friend started trying it out. I said to my friend he must buy it now because it is her favourite. Implying her opinion matters. I did find her cute.

now everytime I walk in and browse or buy soemthing, she will look and try not to smile to herself. And then I will look and also try not to smile. And we are both trying to not smile then she look away trying to hide it.
other times if she sees me she will look to see if it me. Look at me if I don’t look. Or if she sees me in the gym and she with her friend , her friend keep looking , or she keeps smiling to herself or her friend. Also her friend seems to inform her when they see me. I once ask if she using a weight and she answered and when I walked off she was kinda giggling to her friend.
and I spoke to my friend about her saying she cute and I think she over heard because she was smiling to herself. Why does she do all of this and why does she smile to herself always
