You don't need kids to have a loving relationship. Assuming you need to have kids to be successful is stupid.
But to start a family, you need to have kids in one way or another (Though there aren't many options :o). Not everyone starts a family and that's fine, but to those whom do that is, more often than not, their success. Many younger folks and even older ones - don't like the idea of starting a family and just settling. Many afterwords, though, find having a child the greatest joy in their life, even if it's difficult. But then, few things that are worth doing are easy. c:
I love babies and they tend to always like me. I dunno if it is because I am super tall or because I have a baby face but every baby I meet follows me around staring at me in awe or they start crying if I leave if they can't walk yet.
The infamous Babyface Visage? :o
Babies seem to like me but only because I don't like them. It's like how cats intentionally follow around people who don't like cats. It's a real pain in the ass.
The babies, they smell your fear.
