Beep, Beep No Sleep

Last night i was awakened by an electronic peeping. My bedroom furniture, with the exception of my bed, is all in the extra bedroom. I staggered into the extra bedroom and turned off the clock alarm. I was barley back in bed when the beeping started once more. Back to the bedroom and pushed buttons on the phone. Just back in bed and it started to beep again. This time I put on my glasses and turn on the light. The clock and the phone were both unplugged and had been all the time. The beeping was caused by the phone battery needing to be charged. I plug it in and went to sleep! I hate a mystery in the middle of the night!
