What is the note on your parents' mobile phone?

I changed it several times, and then I spoke slowly.

When the university just had its first mobile phone, the notes saved for parents were mom and dad, which was quite satisfactory. I didn't think too much at that time. After all, smartphones were just popular at that time, and I didn't have any special ideas.

Later, when I was a sophomore, my parents and I had differences and had a long cold war. At that time, I directly deleted my dad's phone and blocked it, but my mom didn't delete it, so I changed her note to 0. I don't know why I gave her a note of 0, which was purely random.

Later, after I stayed in Japanese class for a while, I changed my mother's notes to "ぉかさん" and my father's notes to "ぉばさん". It means mom and dad.

This note was always used in my work, and later I changed it to mom and dad for my parents. I don't think it's necessary to make too many articles on appellation. Personally, I think this is also a sign of my maturity.
