The first thing I would do is divide the money into HK$20 bills and some coins, so I can evenly distribute them and also easily get some smaller change. The second thing I would do is go to my favourite beauty store, Sasa. There are lots of beauty products there, from cheap items to high-end products. It is endless! I would probably spend about HK$50 on the items I wanted. After that, the remaining HK$50 would have to be used very wisely. I could always spend the money and just call someone to pick me up or I could go home by myself. If I was going home by myself, I would first get some food (on which I would spend less than HK$30). Then I can either take the MTR or the bus to get home safe and sound. That is what I would do if I had HK$100 remaining in my pocket for a day. Maybe shopping would be a bad idea but I am a complete shopaholic! Shopping makes me happy, so maybe it would be a good idea just for me.

I'd explore Hong Kong randomly. Why? Well, spontaneity can be magical; you could discover a restaurant that serves food you've always wanted to try, you could meet amazing people, or you could find a beautiful new location. So follow me on my imaginary journey around Hong Kong!
To start, I'd hop on a tram for HK$2 (money left: HK$98) because trams are so quaint! I'd jump off where there's really delectable local street food, like gai dan zai or mouth-watering fish balls. I'd spend HK$20 to snack on them (money left: HK$78). Then, I'd take a double-decker bus (money left: HK$68) to the airport because the ride is fantastic - you get to cross the Tsing Ma Bridge and see all the little boats below. Also, Chek Lap Kok airport is an architectural delight and is the best airport in the world. Airports are also a great place to make friends with travellers - and friendship is free. Later, I'd take a bus (money left: HK$58) to the Avenue of Stars in time for the laser light show and a bite to eat from Starbucks (money left: HK$20). Hong Kong has a spectacular night skyline; it would be the perfect way to end my day. Plus I'd be left with enough money to get home safely.
No matter how much you think you know a place, you can always find a few surprises. Spontaneous travelling is worth far more than any amount of money - you should try it sometime.
I've grown up in a caring family. My parents try their best to fulfil my wants and they definitely give me what I need. I've learned a great deal from them as well - that not everyone is as lucky as we are and that we should always help people who are in need.

If I had HK$100, I would spend it on buying things for the needy since I have everything that I need. Although that amount can't make a dramatic difference to people who have cancer or who have lost their family in a car crash, it can bring some people happiness. For example, buying a simple toy and giving it to an orphan can bring him great joy and happiness. He would feel special because for all his life he might have been sharing toys with other children, so having a toy that belongs to him would make him feel very happy. And knowing that I'm the one who made them smile would make me happy and tingly all over!
