What if you could undo every regret? An uncomfortable conversation with The Midnight Library

Have you ever replayed your life at night, wondering how things might have turned out differently? The Midnight Library by Matt Haig asks you to sit with that question. Through Nora Seed’s quiet despair and imagined alternatives, the novel explores regret, possibility, depression, and the fragile hope that living at all might be enough. Have you ever wondered if one different choice could have changed everything? You probably have. Most people do. Usually at night. Usually when the world goes quiet and your mind decides to reopen old files you never asked it to keep. The job you did not take. The person you loved too late or too briefly. The version of yourself that felt possible once. You tell yourself that if you had chosen differently, life would feel fuller, cleaner, less heavy. The Midnight Library begins exactly there, in that familiar ache. Not with drama, but with exhaustion. Not with chaos, but with a woman who feels she has quietly failed at everything that mattered.

Does India need communal parties?

I think, it was Tan's post on this blog itself, Republic Day Event, where this question was raised. My answer. YES. we need communal parties even in Independent, Secular India. Now let me take you, back to events before 1947. When India was a colony of the British Empire. The congress party, in its attempt to gain momentum for the independence movement, heavily used Hinduism, an example of which is the famous Ganesh Utsav held in Mumbai every year. Who complains? No one. But at that time, due to various policies of the congress, Muslims started feeling alienated. Jinnah, in these times, got stubborn over the need of Pakistan and he did find a lot of supporters. Congress, up till late 1940's never got bothered by it. And why should we? Who complains? No one. But there were repercussions. The way people were butchered and slaughtered during that brief time when India got partitioned, was even worse than a civil war scenario. All in the name of religion. And there indeed was cr...

Debate : Do the ends justify the means...

Note : Give it all a fair thought before you jot down... Flaming and religion-bashing will not be tolerated. Your participation is gladly appreciated. I dunno if you folks remember this incident; a couple of yrs back, the UPSC exam had a question where the emainee had to assert his views on *revolutionary terrorism* initiated by Bhagat Singh. As is typical of the government, hue and cry was not far behind... Anyway, let us look at some facts -   Bhagat Singh was an atheist, considered to be one of the earliest Marxist in India and in line with hi thinking, he renamed the Hindustan Republican Party and called it the Hindustan Socialist Revolutionary Party. Bhagat Finally, awaiting his own execution for the murder of Saunders, Bhagat Singh at the young age of 24 studied Marxism thoroughly and wrote a profound pamphlet “Why I am an Atheist.” which is an ideological statement in itself. The circumstances of his death and execution are worth recounting. Although, Bhagat Singh had a...
