Dropbox Heart Attack

I use to things called "Dropbox" on my computer. One is a photo sharing program that I think I have used once. The second is the tool I use to submit all my assignment to the University of Guelph. I recently got an email with the subject "Come back to Dropbox!" that went on to say "Recently your dropbox has been feeling kind of lonely" in the part you can see without opening the email in gmail. This was a couple of days after handing in a bunch of things, and I nearly had a heart attack. Oh. That other Dropbox. Phew.
