Melanie (the pseudonym I've chosen for my gf) had always been a heavy sleeper.
She worked a far later schedule than I did, leading to a predicable night owl lifestyle. Mel was many things, but a Morning Person…was not one of them. Combine these two traits and I can and have played video games (Assassin’s Creed 3!) while she was sleeping a few feet away and she didn’t even budge. So over time I had become, in her words…her Sexy Alarm Clock.
