Maybe it's just me and Enigma... (Possible Spoiler)
It's true what you say and I appreciate all of the replies but it's just their haunting, desperate stares whenever the game asks you to pick your party. People like Yuffie, Aeris, and Tifa (I don't think that any of the male characters do this) are sitting there with these bright smiles on their faces like they're thinking "Please pick me! You NEVER use me! I'LL KILL YOU!" I think that Squaresoft employees get a twisted little kick out of laying the guilt trip on gamers. It's not just in this game. But also in FFT. When you give someone the boot (usually those dadgum chocobos that breed like roaches) they can't just leave. They always have to get a final say in to make you feel bad. Saying things like "Are our worlds really this different?" I know that this is the FFVII forum but I guess I'm just realizing that all of the games kind of make you notice that you're neglecting other party members except for those like FFVI where everybody gets a shot whether they suck or not. >Sigh<
