It was really nice to see unprivileged class of our society which lives mostly below poverty line being happy and astonished when you passed the meals to them. They were not expecting this random act of kindness from you. Very well done, Our society needs caring and concerned citizens like you who are polite, caring and have the element of humanity inside them. Your intention is pure and their were touching moments in the video.
But don't mean to demotivate you, the problem of helping poor people is far too complex. Sadly, feeding poor people is not a solution to poverty. Who likes pity from others to get their basic necessitates of life? Everybody wants to earn with dignity, the real solution would be creating job opportunities for these people. Making education accessible. these are very broad subjects but I guess we should focus on these to help poor. So maybe you need to think deep and for long term if you weep for humanity and for poor people. People can benefit more that way. Join some NGO, human rights commission, UN, WHO etc might enable you to work for many or simply building a career in which you could get wide opportunities to help poor would be great as well.
