Voice mail

I return from my afternoon break to find my message light blinking.

3:41 pm "Hey, it's me.  I did something stupid.  Call me."
3:42 pm "I'm on my cell phone."
3:50 pm "Never mind.  I'm getting the oil changed and I forgot my wallet.  I have to leave my cell phone as collateral.  So don't call, I won't answer"
