The truth is, people often lie
When we were young, our parents and teachers told us not to lie. They taught us that lying is bad.
If this is so, why are there still so many lies?
It has been said that sometimes a lie can be a protection, like a 'white lie'. People tell white lies if they don't want to tell the truth because it would upset someone.
But I think it is just an excuse. Mostly people lie because they want to protect themselves.
I can't deny that telling the truth can be cruel. But I think everyone deserves to know the truth. I would rather be upset by the truth than know I'm being lied to.
Lies cover lies. When you have lied once, you will have to lie a second time to cover up the first one. So why not be honest and tell the truth in the beginning?

The benefits of leading the way
Being a leader is not easy. I am a school prefect and am impressed by leaders who are brave enough to speak in front of others.
They lead and organise activities and are not afraid of making mistakes.
Being a prefect was the chance to fulfil my dream of being a leader. But I doubted whether I could be a good one.
I took a lot of leadership training courses. They were very difficult and I often burst into tears. But the training was worthwhile, and I realised that being a good leader is not as easy as I thought.
Being a leader is not only about talking and leading, but also taking care of others.
It is not easy, but such experiences broaden our horizons and help us become more mature.

Migrant workers deserve our concern
I feel sorry for mainland migrant workers. They come from rural villages that lack resources. They have had to work hard on their land since they were children. They do not have the time or energy to study. Also, educational opportunities are limited compared with people who live in cities.
As life in rural villages is so tough, they choose to work in cities to make more money. But because of the unequal distribution of resources between cities and the countryside, they have to struggle to survive.
What's more, as they do not have much income, future generations will also suffer.
This results in a vicious cycle of poverty. They are exploited by employers and cannot fight back without the support of labour organisations.
Meanwhile, the government does not seem to care. It doesn't support people who live in countryside. For example, the only help for people with eye diseases is the charity Orbis.
But China helps other countries. This is ridiculous. It is like parents abandoning their children but making donations to help others.
I hope the central government will take measures to improve the livelihood of underprivileged groups.
Ways to tackle shortsightedness
A Chinese University study in 2003 found that 65 per cent of secondary school students in Hong Kong are shortsighted, while the figure in America is 30 per cent.
One way you can fight the problem is to play ball games. When you play tennis you have to constantly move your eyes, which is good exercise. When reading, make sure you have enough light.
If you do these things over a long period of time, your eyesight may improve.

Easy does it for tobacco tax
I think the new extra tax on tobacco will help to improve both smokers' and non-smokers' health and cut spending on medical services.
Smokers will quit or look for cheaper sources of cigarettes.
The government should increase the tax, but do it gradually instead of all at once. Preventing trading of contraband cigarettes is also very important.
