There is a difference between want and need. I know this. But sometimes they are the same thing. I want a tote bag from Vineyard Vines (to be used as a diaper bag). I also NEED it. You may think I don't need it, since I already have a very good diaper bag. So my definition of need might be different from your definition of need. But I NEED it, regardless.
Don't you want one too?
