How can we be happy?

A friend sent me a story from one of the newspaper in Indonesia (it's in Indonesian).

It's basically about a 'pemulung', which means someones who goes through trash for a living, whose 3 1/2 years old child has died due to diarrhea (cholera? dehydration?). He doesn't have money rent an ambulance or car to take his daughter to bury her. So he took the body by the train. The person works for Rp. 10.000,- a day (Approximately $1.25).

When a big diaaster like a tsunami occurs. Our hearts are opened and we give generously. We must not forget however, that everyday small disasters, disasters of poverty occur every single day. How can we work, play, eat, knowing that someone and their children tragically can not even get a decent's day meal?
