At first, the three teenagers seem like any other secondary school pupils who gossip about their friends when they get together.
But when the topic switches to Hong Kong's controversial national education scheme, a sense of purpose comes over Wong Lee-lee, Luk Suet-yiu and Tommy Cheung Sau-yin.
They are members of the emerging protest group Scholarism, which has about 150 secondary school pupils as members.
The organisation wants the national education scheme to be dropped. The government says all public primary schools must start teaching national education by 2015, but critics call it indoctrination.
Scholarism's activities have not only gained media attention over the past two months, but what they believe is surveillance from authorities.
The group, established in June last year, first gained public attention when a video featuring the organisation's convenor, Joshua Wong Chi-fung, circulated on the internet. The 15-year-old spoke eloquently to reporters about the national education programme after a rally in May, and the video had attracted more than 186,000 hits as of yesterday.
Several high-profile protests recently have been noted by media. On July 2, they were among protesters whose demonstrations forced a halt to a town hall meeting involving Chief Executive Leung Chun-ying.
