I chose my name, Kaci, when I was in third grade. See, I played softball for a year, and there were two or three other people who shared my birth name. My birth name is "Kristina", so at first they were just like, "Okay, we'll call you Krissy." Of course, I rejected that without a thought and immediately told them to call me "Kaci".
Unfortunately, Kaci didn't last for all those years. I mean, I've always hated my name, but people would refuse to call me by any other. Then last year I switched schools, and they let me introduce myself as the name I chose for myself. So half of the people in my school don't even know my real name. In fact my one friend went on vacation with us, and my mom was all "Kristina lock the door." or whatever. My friend was just like, "Who's Kristina?" XD And she was dead serious. It was amazing. I also had a teacher say, "Kaci's not your real name?" to me. xDD I can't wait to have it changed officially!
And on a random note, Kaci is actually based off of my intials, KC. I thought it was clever in third grade, but now I'm kinda...iffy on it haha. But I'm not changing my name to anything else.
