With THAT out of the way, there's some good news and bad news.
The good news: I got my other package I was expecting today. (The LCD Protector.) The lady who now resides in my old room had saved it, and was planning on returning the item to the post office. (Bless her heart.)
The bad news: She did not know where my older package was. (The lens hood.) She did say that she had seen it once before, near the mailboxes, but she did not bother to pick it up. (She must have assumed the package was for somebody else. Fair enough.)
One friendly lad living nearby said he had actually seen it placed right outside his neighbor's door, which makes no sense as that apartment number is not even remotely close to the one I had before. Intrigued by this, I decided to knock on the door.
The woman who answered, said that she did see the package, but had left it outside her door. Do I trust her?
No. Her demeanor was rather aggressive and almost rude when speaking with me, and I could tell quite clearly that she wanted me to leave as soon as possible.
To be *fair,* she still could be innocent. Maybe a random stranger happened to cross by and, upon seeing my package, decided to take it for themselves. It's impossible to know what exactly happened here.
Either way, it's a good lesson learned. When you move, update your address and do it immediately.
(I'm extremely lucky that both of these purchases were small. Lord knows what could have happened if an expensive item had just been left there for the taking...)
