If you mean he says "great", I would watch his manner of saying this. Is he sarcastically saying "great", or does he seem sad when saying "great", or maybe seem happy when saying "great". If it seem sarcastic, he might secretly like you and think he's loosing you to others, or he might be happy for you. Hard to tell if it's sarcastic. If he seem sad, he probably liked you and hate he'll loose you. If he seems happy, he probably wasn't interested to begin with.
She means grr like a growl.
that he doesn't want to talk to you anymore
that he likes you
there isn't a rule that says that
It may mean that she appreciates what they have to say and they carry on a better conversation than the boys she doesn't choose to talk with.
He is maybe intersted in you because boys that talk randomly about topics is just an exuse for them to talk to you.
it depends what you mean by it, if you mean what would they like to talk about with you, then it depends on what she likes. for e.g, music. if you mean what do they talk about when they're together; boys. :)
It means he will talk to you later. Guys say exactly what they mean.
he's probably doing something he doesn't want you to know or be there.
If someone says, "We have to talk", be prepared to hear something serious or important.
It means he needs to talk to her
He will talk to you soon
because they expressing there feelings
