One of my best friends is constantly giving me her status on how small or big her boobs are. She even asked me what size bra cup I was one day. I know I have big boobs and they're definitely bigger than hers. I've tried telling her we all grow at different paces but it's like she doesn't hear me. I don't know if she's in secure or if she wants advice on how I get mine so big. I can't really think of way to tell her I don't care nicely.

What would you do?
