How Often Do You Get Someone Else’s Mail at Your House?

The mail in this picture is mail that was intended for one of my neighbors.  Each pile represents a single house... So basically, we received mail that was intended for three different houses on our block.

It was easy enough to knock on everyone's door and make sure they got their mail.  I'm sure they'd do the same for me.

It did make me wonder whether or not this type of thing seems to be on the rise.  This wasn't the first time this month that we received someones mail.  Maybe it's just fallout as we head into a busy holiday season?

Does this happen very often to you?
