These students should be considerate and not try to hog all available space. I believe librarians should monitor such behaviour and set clear rules against it.

Study rooms are essential to many of us, especially during exam periods. We want to study in a calm and relaxed environment.

Stick to lifts with carts and trolleys

You often see people using escalators while pushing a baby carriage, a trolley or a cart. In these situations, people are usually advised to take the lifts instead of the escalators. Many don't listen.

Yet this is a dangerous practice. A sudden stop in the escalator might make you lose control of your trolley or cart, which could then fall on people lower down. Moreover, babies could be seriously injured.

To keep ourselves and others safe, we should take the lift while carrying heavy objects.

Use Facebook carefully

People concerned with privacy issues on Facebook advise us to think twice before revealing private information about ourselves on the social-networking site.

That's a valid argument, although I must admit I would find life hard without Facebook. I use the site every day and enjoy keeping in touch with my friends there.

But I am more aware of privacy issues and will try not to be too revealing on the site.

The disabled are just as able as us

I am always pleased to see people in Hong Kong help the disabled, such as the blind or people in wheel-chair, on the street. It's a sign of growing understanding of their needs.

Disabled people have proved themselves to be our equals. They can even play sports such as wheelchair fencing and wheelchair basketball. Such activities make their lives more cheerful and meaningful.

But we can do more to help them. The government should provide special vocational training classes to disabled people so that they can look after themselves.

Facebook is a waste of time. Or is it?

Only if you are in denial will you say that many regular Facebook users aren't wasting their time. The site is designed to lure people to it and trap them there with a variety of online games and features like instant messaging.

But Facebook also has its advantages. The site can serve as a platform for learning and broadening our horizons. Several games on it, like Quadsum math puzzle, are educational.

Whether you waste your time on Facebook or use it wisely depends on what you do with it.

Facebook allows large groups of people from around the world to link up, stay in touch and share their interests. By bringing different people closer, it can help build friendships internationally among its hundreds of millions of users.

Promoting understanding and goodwill among people around the world is hardly a waste of time.

In memoriam of a democracy icon

I was saddened by the death of Szeto Wah, who died at the age of 80 in early January. His passing is a great loss for Hong Kong.

Szeto had been a democracy icon for many years. He was deeply involved in various projects aimed at promoting human rights on the mainland. He was a lightning rod for pro-democracy activism.

Szeto set a good example for us all. He liked serving the community and fought against inequality.

We have lost an honest, brave and outspoken politician.
