Cringeworthy pregnancy announcements to SO

Am I the only one that doesn't like all of these elaborate announcements women make to their SO's? I'm not hating, but it just seems like more of a show for everyone else than for their partners. I would want it to be an intimate thing, just saying that "I have something to tell you, I'm pregnant, you're going to be a father!" Can someone maybe let me know why these women make a big show of it? Maybe I'll understand.
