Wrong Address

If you receive mail or a package that's not yours, what do you do with it?

I return it to the courier. However, the elderly lady across the street seems unaware of how to update her address when placing orders, resulting in her packages being delivered to my door. I simply take them over and remind her to change her address, but she hasn't done so.

If it's from the one who lived there before me before 2013 too bad. It's always nonsense or good causes she didn't want to give a new address, so I just throw that away and otherwise it's from a neighbour and I throw it in their mailbox. That's practical in a flat. You don't have to walk.
