I hope you can see the article below...that it's not too small...read it...see my comments below.
This article has so many truths to it, even though it's a little abrasive. The majority of my friends have children the age of my kiddos and understand why I can't return a phone call right away. But I do have some kid-less friends and all-in-all most of my kid-less friends are quite understanding and know that I'm not just sitting around doing nothing. I do feel guilty when it takes me days to return a phone call, but sometimes when I have 5 minutes of "me" time, I'm going to choose going potty or showering over phoning someone.
That and I have phone-phobia.
