Weird female friend.

Oh this is gonna be so ridiculous. I had this friend back in middle school. Soo one day when I texted her that I couldnt come to school cuz I had my first period. For some reason she wouldnt believe me , and legit asked me to send her a picture. I was so confused and shocked at her audacity. It's been ages since that, yet I don't understand the reason behind her asking me a pictures of u know Wt.
