"Do you remember I wanted to make this year doing whatever I've been wanting to do? One on the list was changing my last name!! I've been wanting to do it since I was 20 years old but I've been putting it off because I was busy and I finally did it this year haha. At the age of 27, I am finally following my mother's last name. I wanted to share this with you because this means a lot to me😊"
