All of the sudden

While getting a bite of food at Rubio's before my evening class, I almost told the cashier that name was Ms. A. I had to think about my first name before I could say it. After, I could only think, "When did this happen?" At the beginning of the year, I kept almost telling my students my first name when they asked me what my name was. Last names just seemed so unnatural, but now it's my first response.
