A pigeon builds a roost in my isolated mail box

Very seldom I get a letter from someone.
And I hear the cooing in the mail box.
She has already started making her nest.
'I am sorry dear; You should informed me earlier,
Then I could have paint it nicely.'
'Do not worry my handsome Master still it's better and I just give a shout to the inquisitive World not to send any sad letters here after.'
This kind pigeon's coo make me happy forever.
