The time is so slow......

We start work at 8:30 and end at 3:00, you can see it seems a short time span for us to do the work yet the time is so slow...very slow..my eyes always catch a glimpse of the clock at the left side of the computer lab, What time is it? it's quarter past 10 , it's half past eleven -Yes! it's lunchtime ....What time is it? Is it time to go home? It's thirty-seven past two.. Unfortunately, it's not.........tic..tac...tic...tac.....twenty minutes to go....almost time is up!
