What does it mean when a girl gives a you blank stare a lot?

[Anonymous]

Does she want you to come and talk to her or does she think you're weird. What's a good conversation topic when you don't know anything about her

[Anonymous]

no. if it's blank, she doesn't want you to come over

[Asker]

why does she keep staring at me then?

[Opinion Owner]

because you keep staring at her. she's just returning the stares

[Asker]

i'm staring at her because she's staring at me and sometimes I ignore her and from my peripheral vision I can tell she still looks at me.
