Monday morning around 9 a.m., I was walking down the stairs as you were walking up. I sort of remembered some guy smiled at me, sorry don't remember what you were wearing or looked like, but I think you wore glasses? I was the girl in white coat. I noticed you smiled at me, I wanted to smile back but my mind was thinking about something else so I looked away. Sorry that was impolite. Didn't mean to do that haha
