1. Who have been trained?

 

Scientist fed two mice and trained when they want to eat they click a button

Finally the scientist has succeeded with his coaching.

 

One day, two mice talk to each other: 

- You see, we were trained to be that guy, every time we click the button, he immediately serve food for us! 

- Uh! Yes, we have done our training very well. 

- From now we do not worry about what to eat anymore!! 

 

2. Message 

The boy unilaterally loves a girl but he dare not express.

One day, take all his courage, he composed a lovely message and clicked “send” at 1am. 

Reply to soon, but the boy decided to read on the next day. 

The next morning, the boy opened the message and ... shock: 

"Your account is not enough to send a message, please recharge."
