Oh god, that. When my wife gave birth, she received a "care package" that was just a box with few small items (water and some cosmetics testers, IIRC) and half a kilogram of flyers. I honestly was floored, and my deep hatred for the advertising industry had reached a new level. And then I noticed that the child health book they gave us - an official medical document that we'll be carrying for the next two decades - had multiple full-page ads in it. Because of course it did.
Did I said it already that advertising is a cancer on modern society?
