Although, some may not think this is funny.
I was at work yesterday, and told my HR rep that I was going to need a new shirt. My exact words for my reason were "I'm only going to get bigger". We have a visiting manager from another city in right now, and she was there when I said it. Her words to me were "Are you not planning on going on a diet?"
And then I came out to all the people that need to know at work. I mentioned it to my manager today, and she gave me a wide eyed look and started laughing. She was a little shocked that the other woman said it.
Personally, while I do think it was a little rude, I don't even mind. I know I'm going to get much worse when my bump rounds out.
