My Single Mom Life

The mail came, and none of it was mine.
My mailbox has HUGE numbers on it, my name is clearly written inside my mailbox, as a matter of fact, it says 'COOPER ONLY' on the inside.

What came in todays mail?
9 pieces of mail for a house 3 doors down.
A name on the envelopes that doesn't even remotely sound, or even spelled close to COOPER.

I called the post office and asked if my route has a new driver.
The guy who answered put me on hold, then came back and said yes, and asked me why.
I explained that I received mail for a house name and number, 3 doors down, and none of my own mail.
He said he'd report it to that drivers supervisor.
I said ok, that's all well and good, but where is MY mail?
I am expecting tax forms and other important documents this week.
We take the mail that isn't ours, and give it to the rightful owners.
Other people don't always do that.
They sometimes throw it out, or write return to sender on it.
If some of these papers I'm expecting get returned to sender, it's going to cause problems for me.
These are time sensitive documents.
I need them.

The guy said he doesn't know where my mail is, but the supervisor will deal with the new driver and tell him about his mistakes.
That doesn't answer my question, all I can do is hope my mail is not lost.
