How old were you when you learned what your parents' first names are?
I honestly can't recall when I learned my parent's first names. I do remember thinking at a young age that their name was actually mom and dad.
Have you ever referred to them by such?
My mother is deceased, but I always have and always will refer to her as mom. As for my dad, the only time I ever called my dad by his first name is when I'm angry at him. I'm rather rebellious when it comes to me being angry with someone and I do it to intentionally bother the person because I'm immature.
For the fun of it, does anyone have any weird names they call their parents (other than the usual variants of Mom or Dad or their first names)?
I've never used any other weird name for my parents. Sometimes I call my dad father, but that comes with me being angry with him as well. I usually say it in a sarcastic tone. I do, however, refer to his pride and joy -- his car (which he refers to as the Eagle Mobile) -- as the loser cruiser... and rightly so, as far as I'm concerned.
