There's this asian lady that works the checkout counter at a chinese carry-out nearby, and she's not bad looking. When I first started seeing her I thought she may be the type who doesn't like americans or she just seemed to be in a relatively bad mood most of the time, not too bad, just a little unpleasant. Then one day, out of nowhere, when my food is ready she's all smiles and comments on how fast my food was prepared.
I was a bit shocked that she was being so ******dly friendly. I thought it was because she was probably used to seeing me, but the following week, she was back to her old self. Then, again, I come in on another day and she's really polite, smiling and everything, and says "goodbye" when I leave.
It seems "cyclic", could it be that when she's pleasant she's ovulating?
