The Case of the Mysterious Necklace

Every woman likes new jewelery, right? Well, I borrowed my roommate's key when I got home from work tonight and picked up the mail. I was kinda freaked out to find an envelope with my name on it from a guy who's name and address I did not recognize, though clearly he knew MY name and address... Somewhat confused and apprehensive, I opened the envelope and out fell a necklace! It's pretty and all, but kinda freaky, considering that I have no idea who sent it!
So, I start to think that I have some creepy guy that knows who I am and where I live. I decide to do some investigative work and google his name and address until I come across a myspace page that pointed me in the right direction. There was a guy on there with the same name, from the same city, who happened to have a link to his ebay store on the page. Bingo. : )
I went to the page and low-and-behold, what should I see but necklaces that looked quite similar to the one that I now held in my hand. So now that I had figured out where it had come from, the question remained - Why? And how did he manage to get my address since I had never ordered anything from him before? Why bother sending free jewelry without some kind of business card indicating your ebay store, if in fact he was doing some unorthodox self-promotion?
Then it dawns on me. A friend of mine had told me that he was going to be sending me something. He asked me this morning if I had gotten it yet, but I said no and asked him if it was coming in the regular mail or a delivery package. (Since I lost my keys awhile back, I don't have a key for the mailbox and have to rely on my roommate to pick it up, so if anything had come, I wouldn't have known.) However, he told me that it should come in a box or something, not the regular mail. So I had been waited for a box from my friend, with his name and address...
Now that I can put my mind at rest that I did not just get jewelry from some strange stalker, I am going to go to bed...
But I think I am going to send this other guy a message that he should be more professional with his packaging methods. Doesn't quite send the right impression to get jewelry in a plain letter envelope (that got quite tattered in the mail due to the hard object inside!) that doesn't protect the contents at all! Just a thought, if he is trying to run a successful business...
