The context of the following conversation is Sydney wanted to talked to Riley, so they wanted for them in the hallway after class.:
Sydney says Hey Riley, where have you been? I need to talk to you so I've been waiting here for you since the last bell rang..
The friend responds Oh, sorry, I had to stay after in my last class for a few minutes to get the assignments from my teacher that I missed when I was out last week..
Sydney responds That's okay, do you have a minute or do you want to walk home together? I really need to talk to you..
The friend responds Sure, we can walk home together. What do you need to talk about? It seems as though it's really important to you if you waited for me after class..
Sydney responds Well, it's important to me anyway, and I hope that you take me seriously when I tell you what I need to talk to you about..
The friend responds If it's that important to you than it's important to me, after all, we are best friends. So, tell me what's on your mind..
