Well, as of 3:52 PM today:
"A CORRECT STREET NUMBER IS NEEDED FOR DELIVERY. UPS IS ATTEMPTING TO OBTAIN THIS INFORMATION"
*wags finger at sender, whoever they are* If you had verified my address with me before you sent it, this wouldn't have happened.
Told you so.
As it turns out, Hookmarks must be related to Charmed And Dangerous, since the mysterious gift was actually a dragonfly charm necklace I had ordered from them last week. I did give them my right address when I placed my order, but whoever filled out the UPS form made the error.
Whatever. I have my necklace. I am happy.
