Girls, girls giggle and hide their faces?

Why do girls giggle and hide their faces when I'm around? I want to solve the mystery of female behaviour

For some girls, its like someone goes to punch you in the face and you flinch. You dont do it purposely, its a natural behavior.
Some girls breathe heavily when they laugh, and maybe they dont want to slam your face with their lung air.
Some girls do it because it makes them feel cuter.
Some girls open their mouths very wide. Like black hole. And that makes them feel embarrassed. (although I dont see why, no person should ever be shamed for being happy)
Some girls have been insulted and now they feel they should. Me for example, I was told I have an ugly smile, and now when I laugh or smile, I tend to cover it unless I am with someone I know genuinely loves me.

Every girl is different. Female behavior is weird.

But why do you do it when I walk by? Attraction?

-They are attracted to you.
-They feel embarrassed.
-They consider it "cute" & feminine.
