Where does Akash Stay?

Dear Priya
This is my fourth letter.  
I hope all my earlier letters dropped in the box  reached , but
The postman might have forgot to handover you,
The Postman might have used  for his soulmate
Since i have not used to use your name at top
And mine at bottom.  
This is again sending with no hope for reply
Yours,
 Akash, Delhi
The letters were in the hand of Priya, all the earier letters of Akash  
Were perfectly reached to Priya could remembered all the words  
And discussion, in the first letter Akash,the bird watcher , talked about  
 Oriental Magpie-Robin, and wrote: This species is 19 centimetres (7.5 in) long, including the long tail that is usually held cocked upright. It is similar in shape to the smaller European Robin, but is longer-tailed. The male has black upperparts, head and throat apart from a white shoulder patch. The underparts and the sides of the long tail are white. Females are greyish black above and greyish white. Young birds have scaly brown upperparts and head. It is the national bird of Bangladesh.
That letter still in the cage of Priya...
In the second letter Akash was tempted to talk about Indian Myna (Acridotheres tristis): He wrote:
In the evening common mynas gather in large flocks to roost, usually on banyan tree. Their noisy calls continue until dark. They begin their calling in the morning before dawn and stay in the roosting tree for a time before they leave to begin feeding.
Why Aksh wrote about birds not about priya...Priya wondered but kept all the letters in the cage but not replied
Priya is in anger and weeping
Why in all the letters Akash has not given His Address  
Why Priya forgot to ask the phone no and address while they met
At  the Railway Station in last summer ,
The solitary reaper Priya wrote many reply but could not post
And this will be kept in cage and cant be replied
Since Akash finished with the words Delhi, without address
Delhi is big city having Big Sky , where Priye will fly and  
Get the nest to rest  
Where does Akash Stay?
What is your address Akash?
Priye wept again...
