"All because two people..."

"All because two people fell in love." For some reason, this phrase is starting to grate on me. I've been seeing it a lot lately since I have fallen into the world of nursery and pinterest. That coupled with my obsession with babycenter.com makes it pretty clear that that is not how every baby is created. It's more like "all because two people decide to have the sex." It is preferable that the baby is born into a loving and stable household. That is not always the case. It just seems so sentimental and trite. And I'm not the sentimental type by nature. Plus now it is being kind of cliched and hackney. Not my thing at all.
