As a Mumbaikar, as an Indian, and as a global citizen, all that I've done in the last one year (other than blogging about it a few days later) boils down to: (a) casting my vote diligently when elections were held, and (b) speaking to the local MLA once (at a meeting he had requested for, with members of the housing complex that I live in), about security in the post 26/11 world, and other issues that were specific to our neighbourhood and local community.
I have no moral right to criticize those who haven't done 'enough', and I have only words of appreciation and gratitude for those who've actually done something constructive about it, whatever that may be.
Of course, I continue to hope and pray for a world that chooses to eschew hatred and embrace love, eschew anger and embrace compassion. And in my own small humble sort of way, I spread soft and gentle messages of peace and harmony, where and when needed.
You do what you have to.
