What does it mean if this girl starts acting cute/girly around you?

Anonymous
- She is usually shy and doesn't talk to any one at work (including me unless I initiate)
- She calls things "cute or pretty" around me: "It's so cute or It's so pretty"
- When I tell her a story, she says "Awww..."
- When I pass by her, she smiles and sometimes looks down while still looking at me
- Tends to say sorry and is extra polite to me "Can borrow your pen please? Thank you"

Is she just being polite or just comfortable?
