Yes, I did know that she was "fictitious" I was "pretending" she was real as that is what you need to do also right?
I think your best bet to get an A on this assignment is to go for the "she's not overweight" angle and that if she wants to lose weight, she can drop a few lbs just by small changes in her eating and activity levels...go for healthy and comfortable, not necessarily slim and unhealthy you know? It is an odd assignment which is why I think the teacher is looking for something different than weight loss. I think the teach is trying to make you reevaluate your ideas on weight and health. Either that or the teacher is wacky!!!!
