I was awakened about 2 am by the ringing of the telephone by my bed. The hotel manager announced that my room-mate had arrived. We briefly introduced ourselves and I went back to sleep.
Melatonin works well, but it is no match for a chorus of barking dogs. It started about 3 am and went on for about an hour. Every dog in Delhi seemed to participate and you could hear the barking roll off into the distance as other dogs participated. Then it came back to our area with a vengeance. It was an incredible performance and all of us who were on the street side of the hotel heard it.
Welcome to Delhi.
