Why does This outgoing girl looks at me with a sad face expression?

Anonymous
There's a girl in my class in college. I know her for a 1 year and a half and we don't have any conflict or anything. She's a pretty outgoing kind of person, always seems to be smiling. But when I talk to her or mke eye contact with her, she just puts on a sad face, like there's something that makes her sad when meeting me. I noticed that this only happens with me and no one else, and we rarely talk to eachother and I never try to talk to her or anything. Any ideas?

FYI : I didn't do or say anything to make her feel that way
