You're always so intuitive, Lisa! I enjoy reading your commentary. We must always remember Caleb is not always rational Anyways, I try to not answer too many questions because I'd rather the story speak for itself, but I'll breifly discuss Joey's behavior. Yes, Joey is Carson's older brother. I tried to imply that he is sort of dense, or at least people view him that way, maybe that wasn't clear. In my head, his trouble comes from the fact that Jake and Caleb (especially Jake) are his friends and he feels "out of the loop." He knows people view him as dense, and he feels Jake especially has capitalized on this by trying to pretend like Joey doesn't know about his activities. BUT it's also that Joey and Carson and Caleb grew up together, and Joey feels like he is ~protecting~ Caleb from Jake's promiscuity (something that Jake thinks he doen't know about, but that is, as shown, kind of a running joke). His actions may or may not be appropriate, but I think his feelings are valid.
Oh, and I'll NEVER do anything fantasy, sci-fi, etc. I don't enjoy reading that and I don't know if I could write it. I'm firmly planted in realistic fiction! Maybe my next story will be adults, though...
