I am a paranoid person in that as I walk down the subway platform and see people on their cellphones scribbling away, I get worried that they're working on their magnum opus. I'm not working on a magnum opus - is coverting oxygen into some sort of semi-poisonous gas not magnificent enough?
What is a magnum opus anyway? Maybe I'm dirty minded but when I hear magnum, I can't help but think of a bunch of condoms, dirty, on the floor beneath a sagging, happy dick. A magnum opus must be greater than a magnificent condom, well used.
Put another way, what I imagine everyone typing into their cell phones on the subway are doing is greater than the best safe sex ever had.
You can see why a girl might get a little paranoid about being left out.
