No, that isn’t the sound of sleeping, much as I wish it were. That is the approximate coming and going of a damn mosquito. Somehow one is in my room, waking me every few minutes as I hear the buzzing in my ear. And every time I turn on the light to look for it, it is in vain. It must be invisible or hiding somewhere, fat and engorged with my blood and most of my patience. I thought Mexico City was supposed to be at too high an altitude for this kind of bullshit.
