Are YOU My Mail?

We don’t have a mailbox at the apartment.  We have a window-sill, and it is the ‘mailbox’ for everyone in the building. 

There has been a letter sitting in the ‘mailbox’ for the last week.  Other mail has come and gone, but this one remains.  Mark and I are wondering, “Are you my mail?”

Our ‘Mailbox’ with the lonely letter sitting in it for a week.

There is a good chance it is addressed to our apartment, but meant for the previous tenant … we are still pondering.
