1. Here's what I did.

Wife got hers and along with it where 3 others all to another resident next door. The best thing I thought I could do is walk right over, knock on their door and hand them over.
A day later at the post office, I pulled a clerk over, that I kind of know and let him know. Told him I didn’t want get anyone in trouble and make any kind of big deal of it. He said this is really serious and he’d speak to the carrier. He then thanked me.
