The title statement never, ever precedes something kind. Have you ever noticed that? Any sort of statement where someone is disclaiming their thoughts, such as "I hate to be rude...", "I don't mean to sound like a bitch but..." or "Sorry to be blunt but...", usually is in front of a really inappropriately rude comment.
Keeping that in mind, I want to touch upon pregnant women for a quick minute. No, I clearly do not know what it's like to be pregnant. I do not understand how tired it makes you, how uncomfortable you are, what sort of anxiety you have, what it feels like when a baby kicks, etc. I do, however, know that being pregnant was your choice (and something that many, many women, no matter how hard they try, can never accomplish). With that in mind, could you please stop talking about/complaining about your pregnancy with people who do not know what it's like? Sure, I will sympathetically nod my head and say "Oh wow, I'm so sorry your baby is kicking your ribs", but the appropriate answer is "Thanks...so, did you watch Lost last week?" We do not need to continue to talk about your pregnant belly.
Once...just once...I'd like to say "I hate to be rude, but I really don't care about how uncomfortable your pregnancy is..."
What do you think would happen? I have some ideas.
