Lack of caffeine VS Lack of sleep

As Adam was walking out the door this morning for work I teased him that he must've gotten enough sleep since he didn't make any coffee.  That NEVER happens, by the way.  He said he didn't even realize it until I mentioned it, but since he was already on the front porch he wasn't headed back in.  I kissed him goodbye and went back in to make the kids breakfast.  I just headed back to our room and saw his cell phone on his night stand.  I guess it was the opposite - he was ESPECIALLY sleep deprived to forget both of those things!
