OMG have you ever tried to wake a teenager when you are at work and they are warm and snuggly at home in bed?
Well let me tell you it is PURE HELL!
You would think that since they can hear a phone ringing from the other end of the house when they are wanting their girl friend to call, that the phone BESIDE their bed would wake them in the morning, but NO!
It takes a good 30 minutes of constant calling to get them up!!
