Overheard, while walking the dog

"Jessica!"
"What?"
"Are you still on the phone?"
"No!"
"I thought you were going to help me plant the lettuce!"
"I am!"
"Well then, get out here!"
"Okay!"

...

"Jessica!"
"What?"
"Are you still on the phone?
"No!"
"Don't lie to me -- are you on the phone or not?"
"I'm almost not!"
