definitely
As you said she corrects your private conversations and stares at you, I am confident that she likes and wants to talk to you.
Most people try to listen in to the conversations of others, whether it be a boy/man or a girl/woman. But as you have queried for why boys listen in, it may be because: A person likes to be 'in sync' with the ones they like, and to know if they like them back. The boys who listen to your conversations might be curious what you're talking about, maybe you would be talking about them. Its a natural tendency of people to expect somebody they like, to mention something about them at some time. And so they try to listen in. On the other hand, it might be pure nosey business, the boys want to know about you and your activities. Which is breach of privacy.
After you have had a few conversations and maybe hung out once or twice.
He likes a girl that has a great sense of humor and that will listen to him.
If the girl likes it, then she should follow her likes, so no, it's not weird!!!!
If she is your friend then it is axiomatic that she likes you.
Ask her what she likes and listen to what she says.
Get her something that you know she likes. Listen to what she talks about and eventually she will mention something that she likes, or is interested in.
depends on the signs :P lol if she is always laughing at what you say then she does, or even if she starts random conversations with you.
Talk with her. Not TO her- with her. Ask her about things she likes- and why. LISTEN to what she says. You talk 20% you listen 80%.
You can't listen to other teams' conversations unless the game glitchs, as it has for me twice before.
