Sleeping in cardboard boxes and rubbish bags on a rainy Saturday night is not anyone's idea of fun, but fun wasn't the goal of a group of students from Hong Kong International School. Fifty-five students from the school chapter of Habitat for Humanity spent the night in boxes and bags last Saturday to experience the hardships homeless people face on a daily basis. The students formed groups and built their own rough shelters. The sleep-out, in its fifth year, raised funds for Habitat for Humanity, an international NGO devoted to eliminating homelessness. Prior to the event, participants raised sponsorship money and provided information about what the organisation does. After taking part in the sleep-out, participants expressed a renewed sense of appreciation for the roofs over their heads. 'People are living under conditions that are so many times worse than our simulated ones, all year round. We do it for one night,' said senior Andrew Mhermann. 'It really does make you appreciate what you get to use every day.' Alexandra Dolan, another senior, said: 'Having to huddle together under trash bags and soggy boxes while it rained - that was the real learning experience.'
