she's interested in you
it probably means she likes you and you should say something to her
No, because what if the boy asks a guy and what if the girls asks a girl? So the answer is no, but it depends on how the person will look when asking the question.
it possibly means that the girl likes YOU!
They like you
that may mean that he likes u or that he is helpless or needy
it means you like him but if he asks you to then he likes you!
That means he girl likes you and answer that question by telling the girl something she likes to do. If you don't know what the girl likes to do then you're a goner
if the girl and your sibling are the same age or the girl is younger, it could mean that the girl wants to get to know you to get closer to your sibling. If your sibling is a girl it could mean she idolizes her or something like that, (or shes a lesbian and the same as above) Otherwise she could just be making conversation hope this helps :)
sometimes it means that they like u or they like someone else.
She wants to talk to you, probably.
Dude, she likes you.
It can mean nothing. The girl is just trying to be helpful. If the girl smiles and looks giggly while passing the sharpener than she my like you.
