Go out for walks in the morning and evening.
Go to the orphanages or old age homes, quite a lot of lonely people are waiting to befriended here.
Go to nearby religious places and observe the people around. Approach the person you like to talk on some pretext or the other.
If you like speaking, you can visit Toastmaster clubs in and around Delhi.
Actually many options are there, I have been on the move on past 7 years and I have friends all over India, and making friends is not that difficult even when we are adults, though not as easy as when we were kids, it is just the approach that matters.
Happy to help. :) http://bit.ly/4uzQtRK
