Mysterious Bug Bites

One of the things that is soooo awful about dorms is that every now and then one might wake up with mysterious bites. I currently have three on my foot, and several more on the back of my neck, all of which itch. Whether or not these bite like bumps are from bugs is up for debate. Theres just something about living in a new place where the population is predominately made up of people that are teenagers. This along with the fact that how many other people have lived in my dorm room and slept in my bed before me, can contribute greatly to the feeling of dirtiness. This is not true for all dorms, i am sure, but for mine it is. However, one other problem is that i also live in an air-conditioning free dorm. That really sucked like three weeks ago, but now that it has gotten colder outside it is a lot nicer. The reason i mention the air-conditioning is that it means that we have to leave the windows open 24/7. I have a theory that bugs are getting through the poorly fitted screens. My bed is right next to the window which explains why my room mate does not have any bite marks. I really hope they are from mosquitos, becasue i dont want bed bugs. In the mean time, though, i think i might wash my sheets, just in case.
