Mum. Mum, Mum, Mum. You know, some people actually think it's funny that I call my mom Mum. I don't really know why; but I've had two of my best friends laugh when I say it. Hmmmmm... What am I supposed to call her?
Mom somehow seems a little bit longer; I think it's probably because you have to shape your mouth more with an "Oh" sound than you do with a "Uh" sound. So I can't call her that... I'm too lazy.
Mother is reserved for getting her attention and thanking her. This is how a typical "Call for Mum" goes: "Mum. Mum! Mom! Momma! Mother! MariLou!! Hey! Sister Conner!" At this point she turns. Also, Mum has trained us to use Mother when thanking her for something. "Ready kids?" she'll say. We all respond simultaneously: "Thank you, Mother-Dear." It must be accompanied by "Dear" or it doesn't count. Besides, if Mom is long, Mother is never-ending!
MariLou and Sister Conner would just be ridiculous to use on a regular basis. Unless of course I am trying to call for her. But I've already gone over that. It just doesn't sound right to call the woman that raised you by her actual name. I don't know why; it just doesn't. I guess it's because she raised you. I mean, that sets you above the average crowd in her book. It would be nothing short of insulting to both Mum and her children if we called her by her name without due process.
Mum really is the perfect way to describe her in one short word. Nothing else is really needed. Nothing else is truly worthy, except maybe Mumma, to be used over and over again. (Never "Mommy".) In short: I love my Mum.
