Dear Prudence,
I live in an apartment with cluster mailboxes and have been receiving my neighbors junk mail. If it is just junk mail, do I have to give it back to them or can I just throw it out? I figure they’d probably toss it themselves but I feel weird doing it. At the same time, I don’t know them, and since the mailboxes have keys, I would have to go knock on their door at a time they were home to give it back. This is graduate student housing so we all have weird schedules which makes that more complicated. If it was important mail, of course I’d make the effort, but do I have to for junk mail? USPS might deliver through rain or snow or whatever, but I didn’t sign up for this!
