Better not give them any money even if they appear genuine. If we really want to help, give money directly to charity or orphanages. We can even donate packets of Milo or diapers to orphanages or even have a simple lunch or dinner treat. It doesn't have to be expensive or grand donations.Sometimes I feel like want to help those who are begging for help, in case one is a genuine case, but too many cooks spoil the broth. I was conned most of the times rather than helping, so sorry nowadays i would just open my bare palms and tell them I, am not much better, need help from others too. If lucky (or unlucky) enough, you will meet a handful of them in a day and burn a big hole in your wallet in helping them. Maybe next time when meeting them again, I'll just ask the police to bring them to Social Welfare Department for help, if they are genuine they won't run away the instance they hear about it.
The best is to call the orphanages and ask what they need urgently. My wife recently donated food items and clothes to an orphanage in Kajang. And while we were there, some family treated all the kids to a simple lunch.
