Before one month i was doing work on computer in the library one Girl came and sat beside me and she started doing her work. After few minutes I had casual interaction with her I didn't asked her name or number and I left library .last week I was sleeping in the library after 10 minutes librarian woke me up. That girl was siting beside me she said Hii and asked do I remember her after that we had good interaction.I took her out in the campus for evening walk we had quite engaging talk before leaving I asked her she gave number with very happy face. Next day I tried to call her but that number doesn't work. Tried 3-4 times but no luck
