Always when I'm with my mom and my kids, I can't help but think, she's watching me. While on the whole I think my mother generally approves of the job I do as a mother, I know what she's thinking:
"You talk too much."
I'm not a "explain instead of discipline" kind of mom - who uses explanations as a way to tell her kids things without having to actually MAKE the hard choices around discipline. I'm not one of those moms who says "okay?" at the end of everything as if she will change her mind about the request for the thirtieth bowl of cheerios for the day if the child says no when she says, "We're not going to have any more cheerios now, okay?"
But--I explain things to my kids. Quite a lot. And in great detail. I don't do this with everything, but often. I do this because I have found when I give them knee-jerk replies or grand, slightly arbitrary guidelines like, "Don't bug me when I'm on the phone," they can't keep to them.
But, if I can take a minute out of my life to explain, "Look, I was on the phone for three minutes TOTAL. During those three minutes, you each interrupted me five times. (I wish I were joking but this is a retelling of Actual Events.) I can't give the other person on the phone my full attention with those constant interruptions, and it made me feel bad, too, because I couldn't give you my attention either. Instead I just felt annoyed and I was short with you. Can you pleassssseeee use your manners when I'm on the phone and either write down your question, or just wait because most phone calls don't take very long to complete. Okay?"
In this case I actually hope for some sort of acknowledgement, so the okay might slip in, though because I hate it so much I usually use another word or phrase like, "Do you understand?" or Capice (which I hope is actually how the italian word for "understand" is said/spelled, because otherwise I've been saying "flaming hog balls" or something ridiculous for years because someone once told me it was Italian for understand.)
 Yes, cell phones and cordless phones are great for providing data should you need to quote a specific time range. You know, if this sort of thing happens in your home. 
 Which I'm sure it doesn't. 
 Because you're perfect. 
 No, you did not detect a note of sarcasm in my voice, okay? 
 Yeah I'm just getting bitchy by now. Your mom probably worships the ground you walk on, too. :P
