A clock without hands
What do we need a watch or alarm clock for? If everybody has a mobile, or update your mobile once a year? You can always check you mobile for time.
You may have a computer in your room, and you always sit in front of your computer, even you have nothing to do, still keep online, keep clicking around, then you want to know what time it is, because your stomach is rumbling. You don't lift up you wrist but look at the bottom-right corner of your computer screen for time instead, because you haven't got a watch on your wrist.
But you may haven't got a computer, and you must have a telephone in your room, it should also tell you the time unmistakably.
OK, you are watching television, you don't want to go to the telephone to check the time, how can you do then? Silly, TV itself can also let you know the time.
Your cooker may have a timer, or the boiler timer In your kitchen cupboard, also displays the time.
Then you plan out and about, you packed everything but your mobile phone , or you have brought it with you, it's in you pocket, but the battery is gone. No problem, you may look around to find a Big Ben on the nearby church tower.
If you can't find one, or although there is a tower clock, the hands always point to eleven O'clock, never move, you know that's wrong, because you already had your lunch at half past eleven. Alright then, you can ask a passer-by.
If you even don't bother asking, or you have tried once, but he/she hasn't a watch, of course, who will bring an alarm clock in his/her pocket? Then you go to a store to buy sweet, the time you need to know is printed on the shopping receipts.
Excuse me, My hands missing!
When my friend went back home, he left me many stuffs which he couldn't take back with him, includes one alarm clock.
One day I astonishingly found that the clock hands were all missing, a clock without hands!
Then I spotted the small hand on the floor, another one was in my daughter's hands, she used that as a bubble blower.
Although the naughty girl has opened the lid, pulling out all the hands, the clock can still "Tick-Tock", it's still working.
