Good Relationships and Toothpaste

Just had an analogous epiphany; how much good relationships are like a tube of toothpaste...
You search and search for the combination of things that are right for you, that make you feel like you're taking proper care of yourself. And once you commit to a certain brand, with the right mixture of brightness and taste, you hang onto it for as long as you can. You sometimes find yourself at the store, in the toothpaste isle, purveying the choices. There are always, and will always be, toothpastes that seem like they're probably better than the one you're committed to. Do you need a different kind? A different combination of taste and brightness? You walk away and proceed to the checkout. You don't need more toothpaste. You still have plenty waiting for you at home. And you will work really hard to keep squeezing your trusty toothpaste out of the tube, night after night.
There will be times, when you open the medicine cabinet, and after seeing the considerably flattened tube, you will question whether or not you need more. But, upon squeezing it, you find that you still have plenty. :)
