Another College Student!
Now that we know a little about the who, let's talk about where. Given previous information, we should answer the question of whether this picture was taken in a dorm room. I'm confident it was not. The layout of the room (lamp reflection) suggest single-occupant bedroom. Not only that, but this picture was sent to me about a month ago, a full 10 days before you could have moved in. Based on a few quick statistics from UST's website, I conclude that you most likely are staying in a dorm the first year.
Now for the fun part. The picture was taken with an Apple Device (Ipad) which, as we know from previous deductions, has a nasty habit of encoding GPS data into its pictures. Without going into too much detail, I was able to get a pretty good lock on your location at the time the picture was taken. This type of information would allow someone to, oh I don't know, find the Facebook page for the incoming freshman class of UST, search for the name "Annie," and narrow the search by hometown. Upon doing that, one would discover that you ARE in fact staying in a dorm (the exact one will not be mentioned), and that you were at one point engaged in the process of searching for a flatmate in true Sherlockian fashion. If the cup in your room (reflection in picture frame) is any indication, you must be quite happy about the number and proximity of Arby's at your new location in the dorms.
