An unexpected rest day today

About 4 am my telephone rang. By the time I answered it, the person/computer had hung up. My son also awoke, and he said his caller ID didn't show anything except that the caller was out of state. I didn't go back to sleep for quite a while and ended up getting 5 hours sleep plus a half hour nap in the afternoon. As a result, I took the day off from running to give my body time to recover from the sleep deprivation.
