What does it mean when I walk into a cute girl and she opens her mouth but I did not hear anything?

A girl who likes you won't be shy
She'll smile and greet you with a hi
She'll blush and giggle, her heart will flutter
So if you walk in, and she don't stutter

It means she's interested and she wants to talk
She'll make eye contact and won't ever balk
At any chance to spend some time with you
It's a sure sign that she likes you too

So don't be afraid to take a chance
And try to make yourself ask for a dance
If you get a yes, then you can be sure
That she really likes you, and not just a lure

It means you stepped on her foot with your construction boots.
