"I don't think my father, the inventor of Toaster Strudel,
would be too pleased to hear about this."
Are you kidding me? First of all this couple wasn't married. I know I shouldn't make assumptions, but one may think it may not have been super planned. Even if they were planning, do you really think that's an appropriate question. And do you really think they are going to answer that on facebook none the less?!
When I saw that post I just couldn't believe my eyes. Talk about the internet developing a lack of privacy. When someone announces they are expecting, through any media, it is never OK to ask if it was planned. If they want to offer that information, fine, but it's never your place to ask!
