At last I saw the missing spectacles( on bed on the bad). On my way to work I feel asleep on the bus, missed my stop and ( must had to) walk back for half a mile. After so many delays I was sure ( at least at last) an hour late , but ( there is) was no one in the office when I arrived. I couldn't understand it. I looked ( at after for) the clock on the wall. It showed eight o'clock! My alarm clock must have stopped the day before.
