My cleaning lady happened on my iPad, which she opened, and saw the black faces in one of these threads. She mentioned this in passing, not in a shocked manner, (she herself is a negress) but more puzzled. Tbh, I haven't pumped out hiphop on my speakers when she's around, usually because she's hoovering, and thus ruins my listening enjoyment.
Anyway, something about black faces emoticons irony suffuser.
