a small anecdote to this --
my friend A (residing in BSB) was in a long distance relation with B (residing in DBRT), back then in 1996 the popular means of communication was writing love letters, so my friend A wrote a letter almost every 7 days to his love residing in DBRT. all was fine untill one fine day the parents of friend B were in for a shock. The postman arrived with 7-10 letters, gift cards etc.
.
There...
more... was some delay on part of railways in WB, and all letters/post cards wrote by friend A kept pilling and turned into sizeable chunk of post by the time delay got sorted out. This pile of letters/post card/greetings blew the lid of their long-distance love story :) :)
