Sleep deprived

Mr M is working night shift.  This afternoon I was getting his lunch packed for tonight.  I opened the "snack" cabinet to get the walnuts and found this bottle of water, partially empty.  I knew right away that Mr M put it there this morning instead of putting it back in the refrigerator.  I told him I'm not  sure he should be driving home after working all night if this is how his brain is working in the morning.
