Long Conversations

So today i went to Melissa's house to get my headphones and ended up spending an hour and a half having a long conversation with her. To be honest i loved it. i prefer the long conversations between me and one person rather than a long conversation between several people. I mean between two people you can talk about so much more, you can express yourself more. for example if theres more than one person and your only confident with a couple of them, then your only gonna be able to express yourself less than you would than with someone you were confident with. the only thing i hate between long conversations is the 10 second awkward silence pauses. These were common between me and Mel, probably because we were both thinking of something to say but I don't know. So our conversation was mainly about college and family however i didn't really care about what it was about all i really wanted was to spend some time to Mel. She told me that she hated school, which shes been telling us for a while, but i honestly don't know what to say to that. i can't tell her to quit and not bother, i can't tell her to get a life and cope with it. I try to help but i just end up asking questions that make me seem like I'm going on. What do i do? My mum says tell her to see about changing to a college but i don't know if you can actually do that. The thing is i want to help and don't know what to do.
