Hi,
When I read PS for the first time, I was always in my dreamland along with the characters…. and had the same feeling on for a long time even after having finished reading the book.
I used to feel like travelling with Vandhiyadevan, spying with Alwarkadiyan, horrified by AK’s death along with Manimekalai and so on…
Several scenes used to come in dreams…. and never got good sleep that time… But however, that was very much enjoyable…
All the topics I speak to people around, will end up in something related to PS. ha ha.. enga veetla ennai oru PS paithiyamnu mudive pannittanga..
