Nothing I suppose. I think if you're worried about starting a family here, because you're worried you may leave those that you love behind, then you're simply missing out. What's to say that you or I will be alive tomorrow even if we do go home? I think wherever you are, you should always live your life the way you want to, and not let the situations completely dictate the way you live it. So if you have a family here, cherish it just as much as you would cherish a family back home. Or don't let yourself be caught up on the idea that either one of you could disappear at any moment, or you'll just regret it when you don't.

... That... might not have been what you were referring to either... but I feel the point still stands.
