Well i was sitting on the computer eating salad and eating grapes.Then all of a sudden the keyboard did not work so then i hit it then it still did not work the i got really mad. so then i went to get water and hoped by the time i got back it would work an d i tried it but it still did not work then i sat down and i split my water and it made a beep noise. Then i hoped it would work but it didn't so i lefted it for a while and i came back about 2 hours ago and it still didn't work so i got really mad then i threw it across the room ( of course it was a cordless keyboard) and then it still did not work and then i really got frustrated and then i just gave up on all my hopes and then i thought about it. I looked at the key board and then i noticed you had to push a button to turn it on. Then i turned it on and then i worked then i was so happy for the rest of the day.
