always a piece or two left over, 

. So what do you do with that piece? 

Do you try to fit it back in? Do you try to make it work? Or do you decide you can live without that missing piece? 

When we go without certain things long enough, it's easy to forget just how much we need them. We forget what we had once. We forget what it's like to live with a thing, not that we need, but that we want. 

That's why it's so important for us to remind ourselves, for us to remember, just because we can live without something, it doesn't mean we have to.
