When my kids call:
"Hi Mom...
"Yes, I know what time it is. There's still a few minutes before we're supposed to be home...
"No, it's going to take us longer than 5 minutes to get there. That's why I'm calling...
"No, Caleb fell, he's hurt...
"No, not that bad. He just took a spill on his bike. Yeah, it ripped his jeans open and he's cut & bleeding just a little bit on the knee...
"No, we don't need a pick up. He's fine. I just wanted to tell you we'll be a few minutes late because we're going to walk home instead of ride the bikes...
"Okay Mom, bye."

"Okay, she bought it. We've got at least 15 minutes more to play before she calls to find out where we're at. Hurry up & rip those jeans."
