So I opened mail that wasn't really addressed to me.

Usually you get a postcard from the post office that says you have an oversized delivery and they’ll hold it at the nearest post office for you to pick it up.

I order bike stuff over the internet all the time, and any parcel too big to fit in the mailbox gets this treatment.

I have a (nonlockable) curbside mailbox and when I get a package that doesn’t fit in it the carrier leaves it on my front porch. UPS does the same thing, except the driver rings my doorbell before walking away.
