Shades of grey?????

I cannot believe how impossibly hard my assignment is!!! Remember when you were in school and you asked the teacher....do I really need to know this and is this really going to help me???? Well I'm there again!! Who would have thought it?? Taking pictures is so easy, right??? Wrong!! Did you know there were things like light meters to learn and white balance and the Zone...and I'm not referring to the celebrity diet!! Everything comes down to shades of grey........(sigh) Talk about tapping out the creativity on this one! ;)
