Alcohol and clock

I always wake up at 7 o'clock and then washing,wear my clothes,I leave my home at 8 o'clock.Last night,my friends and I went to a restaurant and have a great dinner.It's a little restaurant nearly the Town Hall Street and opened till 12 o'clock.we all drunk too much.When I went home,it's 12 o'clock.I felt dizzy and fall asleep quickly.In this morning I felt it's hard to wake up.I heard the clock strike seven,I told myself,"OK,I'll wake up in 30 minutes",I thought I would wake up when the clock strike again.But,when I open my eyes it was 9 o'clock,the clock has stopped, the minute hand did not move,I'm late for work.Hmm.... I think maybe the clock also drunk the alcohol and refused to wake up.
