Those who have never bothered to respond after receipt will henceforth not be sent the rakhis. I have decided to do so because now it is not about them, it is about me:
1. I do not deserve to be treated like that
2. I am better off without them
3. They are not worth my time (or money)
4. A Rakhi means something to me. It also means that the recipient has to respect the sentiments attached to it. If that doesn't happen, I am being unfair to the concept of Rakhi by sending it out to those recipients.
