Preparing a Speech

I've just sat down to write a little piece for a class. Mental note: This is a speech, so write like you talk.
"Good morning everyone - it's always a pleasure to be able to speak in front of...."
Just then I hear someone coming down the stairs. It's my daughter Steph.
"I've got a quick errand to run, can you watch the children for about a half hour for me?"
"Of course" I say, "I'll just take my computer upstairs and watch them while I'm writing."
In a few minutes I'm up the stairs, the computer is on my lap and I'm ready to go.
"Bye" she says.

Let's see, where was I? "It's always a pleasure to be able to speak in front of a group...."
Just then the couch moves a little. Makenzie (age 5) is climbing on my shoulders.
Makenzie! Please!
"Can I ride a little bit..."
No - can't you see I'm working right now.
Ok.
I help her get down.
My hands go back to the keyboard ..... like yourselves....

Di wan two wide too!
That's Elijah, age 3.
"No Elijah, you can't ride too, I just got her down. Not right now."

Just then Faith (age 1) comes over and reaches out to me. I've got to take her. She wouldn't understand. I carefully set my computer on the couch beside me and pick her up. She smiles broadly and we make funny noises to each other for a few minutes. Then, I set her down near her toy box and pull out a couple of her favorite toys. She's happy.
"Great!" I think, "Now I can get back to...."
I feel the weight of Makenzie, who has just jumped on my back, laughing.
"Will you get down, please?" I say.
"Di wan two wide too!"
No Elijah, I just got her off my back.
"Pweeze! Do pwich ups."
"Well, Ok but just a couple."
I lay down on the floor. Elijah climbs on my back and I do a couple of puships. He's hanging on for dear life and squealing happily.
"Ok, I've got to work now..."
"Me too!" It was Makenzie. I do a couple of more pushups with her.
"I wan do lee logs!"
"I can't do Lincoln Logs right now, Elijah, I've got to get back to...."

Just then I realize Faith is nowhere to be seen. Crash! It's coming from the kitchen. I go in there to find that she has pulled out a couple of pans and is banging them together. She smiles at me. I pick her up, put the pans back where they ought to be and bring her back into the living room.
Again I set her down next to her toys. Again, while I'm bending over Makenzie jumps on my back.
"Will you get off!"
"Di wan two wide too!"
"No! You guys just chill. I've got something to do!"
I've notice that my voice has been getting higher in both volume and pitch.
In another moment I'm back at my computer.
....This is something of primary importance to any writer....
Again I feel the same bump. It's Makenzie again climbing on my shoulders, but this time she's got a plan.
"Can I comb your hair Babu?" (That's their name for me.) She's brushing my hair. It feels kind of good..... (I have a very dry scalp, so whenever anyone plays with my hair I like it.)
Thirty minutes later Steph comes in. We're all on the floor watching TV together. My computer is closed and sitting on the couch. Faith is happily messing with my cell phone....
"Thank You!" she says. "Did you get any work done?"
"A little", I say.
"What is your article about?"
"The Importance of Writing Without Distractions."
