Since I've gotten engaged, I'm SHOCKED at how many people ask me how many carats the center stone is/how many carats is in the ring in total. I find that so rude! None of your business! Am I the only one who finds someone asking that incredibly tacky? You could have the biggest, most beautiful diamond in the world and it wouldn't cross my mind to ask you that! I have yet to come up with a response that doesn't upset people too (the first time I literally said "I can't believe you just asked me that" and walked away.)
