Why no sound??

I been looking for a sound that sets the mood for this animatic, but unfortunately, i wasn't lucky enough. Even at the last moment of when class is about to start, i'm still searching. but it's not happening. sounds that i found so far; i just didn't feel like they were going with the animatic. i thought of just throwing something there for time sake, but that would be so odd. so, i didn't attach any audio file. my search is not over yet. i'll find something soon, if it's the last thing i do.
