1) Sneaky tricks
Stalking my favourite idol would be my most pressing requirement. Being invisible would give me a golden opportunity to evade the fans and "sneak in" without being disturbed. What's better than going through the idol's room while the manager and bodyguards handle the chaos created by the fans?

2) Fancy idea
If I were invisible, I would probably go to the nearest shopping centre and try on all the fancy outfits. I know I wouldn't be able to afford them, but it would be great to wear them for even a few minutes. I would also like to take selfies while wearing them. I would be invisible anyway :-)!

3) Hidden fears
I would find a way that would help me become visible again! If I were invisible, my friends would not be able to see me and play with me. I would be very sad if I was alone forever!

4) Time to travel
I would like to travel the world to learn more about the cultures and history of people who inhabit this planet. As I'd be invisible, I would just go to the airport, board a plane, and go wherever I wanted. For example, I'd love to go to North Korea and take some videos of the people and places there. It would be so cool, wouldn't it?

5) Scary times
If you think that being invisible would prevent you from grabbing the spotlight, you're wrong! I would wear colourful outfits so that people would see clothes floating in the air, and most probably scare them silly. Ha ha, I bet I would see some priceless expressions.

6) Lonely feeling
I would feel so lonely and helpless because nobody would see me or hear my voice, including my family and friends. I would first draw their attention by playing some tricks, such as making strange noises or waving a white cloth - just like a ghost. Then we might communicate with each other by using pen and paper and try to find out the reason why I became invisible.

7) Selfie-less life
Since I am not rich and do not have a job, being invisible means I could travel the world free of charge. Being invisible has its drawbacks though. For instance, I wouldn't be able to take any selfies during my visits - but at least I'd have great memories!

8) Seal of approval
If I were invisible, I would do something that I've wanted to do for a long time but haven't been able to. I would go to the post office to see how stamps are made. I love collecting stamps but I don't know their origins. If I were invisible, I would be able to take a lot of photos of the stamp-making process. I think it would be a fascinating experience.

9) Having a ball
Our school football team always lose. If I were invisible, I would be able to help them win the inter-school competition. I would steal the ball and pass it to my teammates, helping them to score goals. I would also help the goalkeeper save every shot our opponents took. This way, there's no doubt we would win the championship.

10) Home alone
I would never cross a street. No matter how careful I was, I'm sure I'd get run over by a car, bus or lorry because the drivers wouldn't be able to see me. And, needless to say, I'd keep bumping into people on Hong Kong's busy streets. So I would just stay at home and do some reading. Think it's boring? You bet! Ha ha!
