I used to use a combination of my last name and my and DH first initials. After a bad internet experience, I needed to change and give myself a new start.
I took the first three letters of our first dog's and our second dog's names. The first dog has been gone for over three years. Her name was Hailey. The second dog, Mia, is seven years old. I do not plan to change the name to add our newest member, Holly. It can always be used if I ever need to change again.
