"It's about as useless as a screen door on a submarine," Rich Mullins once sang. He was talking about faith without works, but the same could be said of arguing with a three year old.
Believe me, I know. I have LOTS of experience.
Three year olds arguing with each other is even more pointless. I have been witness to many conversations between mine, especially in the car, such as...
Suhn: My name is Suhn.
Sean: No, my name is Sean!
Suhn: NO, my name is SUHN!!
Sean: NO, MY NAME IS SEAN!!!
Sean: We are going to turn on my side.
Suhn: No, we are going to turn on my side!
Sean: NO, we are going to turn on MY SIDE!!
Suhn: NO SEAN, WE ARE GOING TO TURN ON MY SIDE!!!
Some times I join in: Be Quiet you two, I'm driving, I'll decide where we turn.
Many times that's the point where they decide to join forces and tell me I'm wrong.
And then a little tune pops into my head and I remember how pointless it is to argue with three year olds. You think I'd learn.
Actually you think they'd learn. How many reminders, consequences, etc. do they need to remember who the boss is? (eh-hem, that is ME just in case you had any doubt)
Someday (soon? please, please, please) they may actually figure out how pointless it is to argue with mom. Until then, I will bravely carry on, enduring the long, arduous, screen-door-on-a-submarine, I-am-right-because-I'm-three type of episodes/tantrums that come with three year olds...
...or I will keel over from the brain exhaustion that comes from listening to one too many pointless arguments.
At this point in time, I'd say its a toss-up.
