Nearly 14

I was 13, a few months shy of my 14th birthday. I was visiting my older (by 10+ years) married cousins, helping them on their farm. I wwoke up one morning with blood on my underwear. Since my mom was a nurse, I knew exactly what it was, so I asked my cousin if she had anything, and she smiled and said, "Sure! You were caught off guard, huh?" I said, "Something like that." It never occurred to me to mention that it was my first one. I didn't think it was that big of a deal. She found out later when my parents and aunt and uncle all met at restaurant prior to me going back home. Mom, my cousin, and aunt were very impressed that I knew "just what to do." Like I said, I kenw it was going to happen eventually, so it wasn't a big deal.
