So we were texting, and we got onto the topic of birthdays. She's about 1.7 years older than me, and 1 grade ahead of me. I already knew this, but then she told me "I don't act my age". I asked her if it was a good thing, and she said it was very good. However, that signals that she has an idea about guys my age that isn't pleasant, and if I screw up, she will attach it to that age.
